Document Type and Number:
WIPO Patent Application WO/2022/064840
Kind Code:
A1
Abstract:
This motor drive device that drives a motor using three-phase alternating current as a power source comprises: a rectifier circuit that rectifies the three-phase alternating current; a current detection circuit that detects DC current rectified by the rectifier circuit; and a crosspoint detection circuit that detects the crosspoint between the current detected by the current detection circuit and a prescribed current value, and outputs a control signal indicating whether to drive the motor based on the detection result.
