Note 1. (1) Guaranteed power supply voltage for operation is 19V minimum and 21V maximum. (2) When over voltage occurs, GDU voltage bus (G-K voltage for GCT) is clamped to be 21V if mamimum voltage for input gata voltage from power supply is 25V and maximum duration of over voltage higher than 21V from power supply is 0.4 sec when control signal is on (Please see Fig. 8). (3) When over voltage occurs, GDU voltage bus is clamped to be 21V with no time limitation if maximum voltage from power supply is 25V and control signal is off (Please see Fig. 8). Note 2. GCT is off state and no gate signal is supplied for gate driver. No leakage current flows between gate and cathode of GCT. Note 3. Optic fiber data link HFBR-1521 and HFBR-2521 are interlocked each other. Note 4.

Note 6. Maximum peak voltage of GDU input voltage from power supply should be lower than 25V. Note 7. If the period for over voltage < 1.0ms (period t1), no fault signal is sent. If the period for over voltage 1.0ms, fault signal starts after period t2 from 22V of power supply voltage. System should be shut down (Control signal should be off) within period t3 from fault signal start. Note 8. GDU Voltage bus (G-K Voltage for GCT) is clamped to be 21V if power supply voltage is higher than 21V after system shut down (control signal off).
