function

1. Drive and Control
   • Convert the low voltage and low current logic signals of the control system into high voltage and high current drive signals, and accurately control the conduction and turn off of IGBT.
   • Support PWM pulse modulation, achieve adjustable switching frequency, and adapt to different load requirements.
2. Electrical isolation
   • Isolated driveUsing optocoupler, magnetic isolation or transformer isolation technology to block the electrical connection between the high voltage side and the low voltage side, preventing noise interference and high voltage crosstalk.
   • Non isolated driveSuitable for low voltage and low-power scenarios, with a simple structure but low safety.
3. protection function
   • overcurrent protectionMonitor IGBT current and trigger protection mechanism when it exceeds the threshold (such as reducing driving voltage or cutting off power).
   • overvoltage protectionDetecting overvoltage signals through voltage comparators to protect IGBTs from damage.
   • over-temperature protectionIntegrated temperature sensor, turn off the drive signal when the temperature exceeds the standard.
   • short circuit protectionQuickly respond to short circuit faults and prevent device failure.
4. state feedback
   • Provide real-time feedback on the working status of IGBT (such as current, voltage, temperature) for system monitoring and troubleshooting.
