Its main function is to receive the square wave signal from the controller, and convert it into an isolated, amplified gate signal which controls the IGBT’s turn-on and turn off cycle. It is a square wave signal through the optocoupler that provides reliable electrical isolation, therefore the control system cannot be affected by the common mode interference caused by IGBT. In addition, the QC962-8A driver can also be used to detect the undersaturated voltage drop of the IGBT collector to quickly identify the IGBT’s overcurrent or short circuit state and trigger the protection function. so as to avoid IGBT being burned in the fault conditions, afterwards the controller will issue a warning signal.
