WIPO Patent Application WO/2020/194623
Kind Code:
A1
Abstract:
This motor drive control device (100) is provided with: an inverter circuit (2) composed of switching elements that control conduction to a motor (1); a gate drive circuit (15) that drives the switching elements on the basis of a driving signal; a first protective circuit (21) that stops the operation of the inverter circuit by shutting off power supply to the gate drive circuit when the detected value of the current flowing through the motor is a threshold value or higher; and a second protective circuit (22) that shuts off an input of the driving signal to the gate drive circuit when the detected value is a threshold value or higher.
