Title:
DRIVE DEVICE, ELECTRIC VEHICLE, AND DRIVE DEVICE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/186759
Kind Code:
A1
Abstract:
This drive device is provided with a control unit for controlling the drive of a motor by controlling first to sixth switches. In a first case where a detected speed by a rotational speed detection unit is slower than a preset first reference speed and a set duty ratio which is set on the basis of the detected speed and a user manipulated variable for controlling the rotation of the motor is greater than or equal to a preset first reference duty ratio, the control unit performs: control for switching the on/off of the first switch by using a first phase high-side PWM signal having the set duty ratio while turning off the second switch; control for switching the on/off of the third switch by using a second phase high-side PWM signal having the set duty ratio while turning off the fourth switch; and control for switching the on/off of the fifth switch by using a third phase high-side PWM signal having the set duty ratio while turning off the sixth switch.
