IGBT DRIVE CIRCUIT FOR MOTOR CONTROLLER, AND MOTOR CONTROLLER

The present disclosure discloses an IGBT driving circuit for an electric-motor controller and an electric-motor controller (300). The IGBT driving circuit includes: a function safety circuit (102) provided on a driver board (302) of the electric-motor controller (300), and a detection feedback circuit (101) and a pulse-width-modulation (PWM) buffer (103) circuit that are connected to the function safety circuit (102). The detection feedback circuit (101) is configured to detect an IGBT module (303) of the electric-motor controller (300), and when a specified malfunction of the IGBT module (303) is detected, send a specified-malfunction signal to the function safety circuit (102). The function safety circuit (102) is configured to judge according to a preset malfunction treating rule and the received specified-malfunction signal, and then output a corresponding controlling signal to the PWM buffer (103) circuit. The PWM buffer (103) circuit is configured to generate according to the corresponding controlling signal a PWM signal that drives the IGBT module (303), to control ON/OFF of the IGBT module (303) to protect the IGBT module (303). The technical solutions of the present application have multiple functions of protection, which improves the stability and the safety of the IGBT, and has quick action and timely protection.
