The function of the 560CMU05  driver circuit is to drive the IGBT module to ensure its normal operation, while also protecting the IGBT module. The function of the IGBT driving circuit is crucial for the entire system composed of IGBT. IGBT is the core component of a circuit, which can conduct under high voltage and turn off under high current. In hard switching bridge circuits, the correct and reliable use of power device 560CMU05  plays a crucial role. The driving circuit is to amplify the PWM signal output by the control circuit to meet the requirements of driving IGBT. The reasonable design of the driving circuit directly affects the safe and reliable use of IGBT. The IGBT driver circuit also provides gate overvoltage, short circuit protection, overcurrent protection, over temperature protection, Vce overvoltage protection (active clamping), gate undervoltage protection, and didt protection (a type of short-circuit overcurrent protection) for IGBT devices.

Design of 560CMU05  driver circuit
1. Performance parameters to consider when designing IGBT driver circuits
1) The peak forward and reverse voltage that IGBT can withstand in the circuit can be derived from the following formula:
When designing the driving circuit, a safety factor of 2-2.5 times needs to be considered, and the voltage of the optional IGBT is 1200V.
2) The peak current that 560CMU05  needs to withstand when conducting in the circuit can be derived from the following formula:
