skyper ? 32pro r 6 rev 0 ? 11.08.2010 ? by semikron driver performance the driver is designed for application with half br idges or single modules and a maximum gate charge p er pulse < 6,3c. the charge necessary to switch the igbt is mainly depending on the igbt?s chip size, the dc-lin k voltage and the gate voltage. this correlation is shown in module d atasheets. it should, however, be considered that t he driver is turned on at +15v and turned off at -7v. therefore, the gate vo ltage will change by 22v during each switching proce dure. unfortunately, many datasheets do not show negative gate voltages. in order to determine the required charge, the upper leg of the charge curve may be prolonged to +22v for determination of approximate charge per switch. the medium output current of the driver is determin ed by the switching frequency and the gate charge. the maximum switching frequency may be calculated with the show n equations and is limited by the average current o f the driver power supply and the power dissipation of driver componen ts. calculation switching frequency maximum switching frequency @ different gate charge s @ t amb =25c f max : maximum switching frequency * iout avmax : maximum output average current q ge : gate charge of the driven igbt *@ t amb =25c 0 khz 10 khz 20 khz 30 khz 40 khz 50 khz 60 khz 0 c 1 c 2 c 3 c 4 c 5 c 6 c 7 c gate charge switching frequency calculation average output current average output current as a function of the ambient temperature ge sw av q f iout = iout av : average output current f sw : switching frequency q ge : gate charge of the driven igbt 0 ma 10 ma 20 ma 30 ma 40 ma 50 ma 60 ma 0 c 10 c 20 c 30 c 40 c 50 c 60 c 70 c 80 c 90 c ambient temperature average output current insulation magnetic transformers are used for insulation betwe en gate driver primary and secondary side. the tran sformer set consists of pulse transformers which are used bidirectional for turn-on and turn-off signals of the igbt and the error feedback between secondary and primary side, and a dc/dc con verter. this converter provides a potential separat ion (galvanic separation) and power supply for the two secondary (top and bot) sides of the driver. thus, external tra nsformers for power supply are not required. creepage and clearance distance in mm primary to secondary min. 12,2 please note: the maximum value of the switching frequency is lim ited to 50khz due to switching reasons. ge max av max q iout f =
skyper ? 32pro r 7 rev 0 ? 11.08.2010 ? by semikron isolation test voltage the isolation test voltage represents a measure of immunity to transient voltages. the maximum test vo ltage and time applied once between input and output, and once bet ween output 1 and output 2 are indicated in the abs olute maximum ratings. the high-voltage isolation tests and repea ted tests of an isolation barrier can degrade isola tion capability due to partial discharge. repeated isolation voltage tests should be performed with reduced voltage. the test voltage must be reduced by 20% for each repeated test. the isolation of the isolation barrier (transformer ) is checked in the part. with exception of the iso lation barrier, no active parts, which could break through are used. an isolat ion test is not performed as a series test. therefo re, the user can perform once the isolation test with voltage and ti me indicated in the absolute maximum ratings. auxiliary power supply a few basic rules should be followed when dimensioni ng the customer side power supply for the driver. t he following table shows the required features of an appropriate power supply. requirements of the auxiliary power supply regulated power supply +15v 4% maximum rise time of auxiliary power supply 50ms minimum peak current of auxiliary supply 1a power on reset completed after 150ms the supplying switched mode power supply may not be turned-off for a short time as consequence of its current limitation. its output characteristic needs to be considered. sw itched mode power supplies with fold-back character istic or hiccup-mode can create problems if no sufficient over current m argin is available. the voltage has to rise continu ously and without any plateau formation as shown in the following diagram . rising slope of the power supply voltage if the power supply is able to provide a higher cur rent, a peak current will flow in the first instant to charge up the input capacitances on the driver. its peak current value will be limited by the power supply and the effecti ve impedances (e.g. distribution lines), only. it is recommended to avoid the paralleling of sever al customer side power supply units. their differen t set current limitations may lead to dips in the supply voltage. the driver is ready for operation typically 150ms a fter turning on the supply voltage. the driver erro r signal prim_hold_out and prim_hold_in are operational after this time. without any error present, the prim_hold_ out signal will be reset. to assure a high level of system safety the top and bot signal inputs should stay in a defined state (of f state, low) during driver turn-on time. only after the end of t he power-on-reset, igbt switching operation shall be permitted. please note: do not apply switching signals during power on reset. please note: an isolation test is not performed at semikron as a series test.
skyper ? 32pro r 8 rev 0 ? 11.08.2010 ? by semikron under voltage reset (uvr) the under voltage reset circuit configures the drive r core to hold in a reset state during power on and power off. uvr can be thought of as a supplement function to the build in power-on-reset by the user. while in reset, the driver is held in its initial condition until prim_npwrfail_in is forced into high state. once the system reset sequence completes, th e driver core is ready to operate. uvr input application hints a capacitor is connected to the input to obtain hig h noise immunity. disabling of the under voltage reset function (prim_npwrfail_in) can be achieved by no connection or connection to +15v. under voltage protection (uvp) primary the internally detected supply voltage of the drive r has an under voltage protection. the table below gives an overview of the trip level. supply voltage uvp level regulated +15v 4% 13,5v if the internally detected supply voltage of the dr iver falls below this level, the igbts will be switc hed off (igbt driving signals set to low). the input side switching signa ls of the driver will be ignored. the error memory will be set, and the output prim_hold_out changes to the high state. under voltage protection secondary this function monitors the rectified voltage on the secondary side. if the voltage drops, the igbts wil l be switched off (igbt driving signal set to low). the input side switchin g signals of the driver will be ignored. the error memory will be set, and the output prim_hold_out changes to the high state. output voltage uvp level regulated +15v 12v input signals the signal transfer to each igbt is made with pulse transformers, used for switching on and switching o ff of the igbt. the inputs have a schmitt trigger characteristic and a p ositive / active high logic (input high = igbt on; i nput low = igbt off). it is mandatory to use circuits which switch active to +15v and 0v. pull up and open collector output sta ges must not be used for top / bot control signals. it is recommended choosing the line drivers according to the demande d length of the signal wires. please note: it is not permitted to apply switching pulses short er than 1s. please note: do not use prim_npwrfail_in to place the driver cor e into halt mode during operation.
skyper ? 32pro r 9 rev 0 ? 11.08.2010 ? by semikron top / bot input a capacitor is connected to the input to obtain hig h noise immunity. this capacitor can cause for current limi ted line drivers a little delay of few ns, which can be neglected. t he capacitors have to be placed as close as possible to the drive r interface. short pulse suppression (sps) this circuit suppresses short turn-on and off-pulse s of incoming signals. this way the igbts are protec ted against spurious noise as they can occur due to bursts on the signal lines. pulses shorter than 625ns are suppressed an d all pulses longer than 750ns get through for 100% probability. pulses with a length in-between 625ns and 750ns can be eit her suppressed or get through. pulse pattern ? sps shortpulses prim_top/bot_in(high) prim_top/bot_in(low) sec_top/bot_igbt_on sec_top/bot_igbt_off failure management a failure caused by prim_npwrfail_in, under voltage pr otection, dynamic short circuit detection or extern al error input will force prim_halt_out into high state (not ready t o operate). the igbts will be switched off (igbt driv ing signals set to low) and switching pulses from the controller wi ll be not transferred to the output stage. connecte d and switched off igbts remain turned off. at the same time an internal timer with a time constant of 3s is started. if no failure, caused by prim_npwrfail_in or under voltage protection is prese nt anymore, a time of 3s after failure detection is passed and also top and bot input signals are set to the low level fo r a period of minimum t perrreset > 9s, the driver core is ready to operate and switching pulses are transferred to the output stage. if prim_halt_out is high state, the ex ternal error input is not monitored. a present failure signal at extern al error input during prim_halt_out in high state is again detected after a reset signal and first transfer of top and bo t switching pulses to the output stage. pulse pattern failure management prim_top/bot_in failure prim_halt_out sec_top/bot_igbt_on/off internaltimer 3s 9s 3s 9s propagation delay of the driver, interlock dead tim e and switching time of the igbt chip has to be taken into account (not shown in the pulse pattern).
skyper ? 32pro r 10 rev 0 ? 11.08.2010 ? by semikron halt logic signal (hls) the halt logic signals prim_halt_in and prim_halt_out s how and control the drive core status. the driver c ore is placed into halt mode by setting prim_halt_in into hi gh state (disable driver). this signal can gather d isable signals of other hardware components for stopping operation an d switching off the igbt. a high signal will set the driver core into hold and switching pulses from the controller will be not transferred to the output stage. the input a nd output have schmitt trigger characteristic. pull up and open collector o utput stages must not be used. connection prim_halt_out and prim_halt_in connection prim_halt_out (prim_halt_in not used) dead time generation (interlock top / bot) adjustabl e (dt) the dt circuit prevents, that top and bot igbt of one half bridge are switched on at the same time (shoo t through). the dead time is not added to a dead time given by the controller. thus the total dead time is the maximum of "built in dead time" and "controller dead time". it is possible to contr ol the driver with one switching signal and its inv erted signal. pulse pattern ? dt the total propagation delay of the driver is the s um of interlock dead time (t td ) and driver input output signal propagation delay (t d(on;off)io ) as shown in the pulse pattern. moreover the switc hing time of the igbt chip has to be taken into account (not shown in the pulse pattern). in case both channel inputs (prim_top_in and prim_bot_in) are at high level, the igbts will be t urned off. if only one channel is switching, there will be no interlock dead time. the dead time can be adjusted and the locking funct ion may be neutralized as shown in the following ta ble. please note: no error message will be generated when overlap of switching signals occurs. please note: a high signal @ prim_halt_in does not generate a hi gh signal @ prim_halt_out. after low signal @ prim_ halt_in the gate driver is enable do operate. please note: prim_halt_out must be always connected with prim_ha lt_in. prim_halt_out is not short circuit proof.
