Title:
ELECTRIC MOTOR CONTROL APPARATUS, CONTROL METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/244276
Kind Code:
A1
Abstract:
Provided in the present application is an electric motor control apparatus, comprising: a first drive module and a second drive module, which are used for driving different coils in a multi-phase coil of an electric motor respectively according to a direct current outputted from a battery; the first drive module is further used to convert an alternating current voltage into a direct current voltage when charging the battery; and the second drive module is further used to convert the direct current voltage into a charging voltage of the battery when charging the battery. When driving the electric motor, the drive modules in the electric motor control apparatus are used to drive the electric motor; during charging, DC-DC conversion is performed by using a portion of the units in the drive modules, thus power supply charging may be achieved without the need to additionally provide a separate DC-DC conversion module, which saves on space and costs.
