Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/155844
Kind Code:
A1
Abstract:
The purpose of the present invention is to easily suppress the influence of dead time on voltage control without requiring an analysis of the specific operation status and the like of an individual motor control device by a user. A control circuit (10) causes a step-down converter circuit (40) to step down a DC voltage to an inverter circuit (60) so that the duty of a PWM signal becomes greater than a dead time (Td).
