This device is a fully isolated gate drive circuit consisting of an optically isolated gate drive amplifier and an isolated DC-DC converter. The gate driver provides an over-current protection function based on desaturation detection.

Recommended IGBT Modules: VCES = 1200V Series up to 3600A Class VCES = 1700V Series up to 3600A Class 1 Powerex, Inc., 173 Pavilion Lane, Youngwood, Pennsylvania 15697 (724) 925-7272 www.pwrx.com VLA552-01 IGBT Gate Driver + DC/DC Converter Absolute Maximum Ratings, Ta = 25°C unless otherwise specified Characteristics Symbol Rating Units Supply Voltage (DC) Input Signal Voltage (Applied Between Pins 6-7, 50% Duty Cycle, Pulse Width 1ms) Output Peak Current (Pulse Width 3μs) VD -1 ~ 16.5 Volts VI -7 ~ +7 Volts IOHP -24 Amperes IOLP 24 Amperes Isolation Voltage (Sine Wave Voltage 60Hz, for 1 min., R.H. 60A Class R1 : 1Ω, 1W Class R2 : 10Ω, 1/4W Class DZ3~6 : Vpn < Total VZ < VCES of IGBT Rough guide of total VZ is as follows: For VCES 1200V Series  900~1000V For VCES 1700V Series  1300~1400V It depends on Vpn, IC(max), RG, snubber circuit inductance of power main circuit, and kind of main condenser. NOTE: 1. Decoupling capacitors should be located as close as possible to the Hybrid IC pins. 2. The gate circuit path should be kept as short as possible to minimize influence of switching noise. 3. D1 requires approximately the same blocking voltage as the IGBT modules. 4. When recovery current flows in D1, Pin 30 sees high voltage. A zener diode between Pin 21 and Pin 30 is necessary as shown in above diagram. 5. If the short-circuit protection circuit is not used, please connect a 4.7k ohm resistor between Pin 30 and pin 20. (D1 and DZ1 are not required.) 6. If the collector clamp circuit is activated repeatedly, it may be destroyed as a result of overheating. For this reason, power dissipation of the zener diode should be determined by testing in the actual inverter. 07/14 Rev. 0 3 Powerex, Inc., 173 Pavilion Lane, Youngwood, Pennsylvania 15697 (724) 925-7272 www.pwrx.com VLA552-01 IGBT Gate Driver + DC/DC Converter Operation of Protection Circuit Adjustment of Output Fall Time 1. When an “ON” input signal is applied for a period longer than Ttrip and the collector voltage is high, the hybrid IC will recognize the condition as a short-circuit and immediately reduce the gate voltage. It will also produce a low voltage fault signal at the respective Pin 29 or Pin 16 alerting that the protection circuit is in operation. 2. The protection circuit will reset if an “OFF” input signal is applied and the minimum 1~2ms shutdown time has passed. “OFF” signal must be 10μs or more. 3. The controlled time to detect a short-circuit (Ttrip) should be set so that the IGBT can be fully turned “ON” before a short-circuit condition can be detected. It is possible to adjust Ttrip by connecting a capacitor (Ctrip) between Pins 18 and 21, as well as Pins 27 and 24. 4. When the short-circuit protection is activated, the soft gate shutdown circuit reduces the collector surge voltage on the IGBT. The gate shut down speed can be slowed even more by adding a capacitor to the CS terminal (between Pins 15 and 18; Pins 27 and 30).
