Title:
DRIVE DEVICE, ELECTRIC VEHICLE, AND DRIVE DEVICE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/186761
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. The control unit periodically sets continuous first to sixth energization periods, each of which corresponds to an electrical angle of 60º, in accordance with first to sixth detection periods. The control unit PWM-controls the first to sixth switches so as to switch between 120º-energization for flowing phase current during continuous two energization periods among the first to sixth energization periods and 180º-energization for flowing phase current during continuous three energization periods among the first to sixth energization periods. The control unit sets an energization period during switching among the first to sixth energization periods such that the energization period is shifted by a period in accordance with the arrangement angle of an angle sensor with respect to a detection period during switching among the first to sixth detection periods.
