The IGBT driver is the device that drives the IGBT and regulates its overall performance. It not only affects the dynamic performance of the IGBT, but also the cost and reliability of the system. The selection of the driver and the calculation of the output power determine the reliability of the converter system. Insufficient power or wrong selection of the driver may directly lead to damage of the IGBT and the driver.
The main functions of the IGBT driver include:
Generating the drive voltage and current required by the IGBT gate.
Protecting the IGBT from faults such as overvoltage, overcurrent and overheating.
Increase the switching speed and efficiency of the IGBT.
There are many types of IGBT drivers that can be selected for different application scenarios. Common IGBT driver types include:
Isolated IGBT driver: has an isolation function that prevents mutual interference between the control circuit and the load circuit.
Non-isolated IGBT driver: no isolation function, lower cost, but higher requirements for the control circuit.
Modular IGBT driver: integrates IGBT, driver and protection circuit in a module, easy to use.
IGBT driver is widely used in inverter, switching power supply, motor drive and other fields.
