Title:
ELECTRIC MOTOR CONTROLLER AND ELECTRIC MOTOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/279747
Kind Code:
A1
Abstract:
Provided are an electric motor controller and an electric motor using same. The electric motor controller comprises a power supply circuit, a micro control unit (MCU), an inverter circuit and a driving circuit, wherein the power supply circuit supplies power to the micro control unit (MCU), the inverter circuit and the driving circuit; and the power supply circuit comprises a rectification circuit and a single-ended flyback-type DC-DC conversion circuit, a mains supply alternating current input is connected to an input end of the rectification circuit, an output end of the rectification circuit is connected to the single-ended flyback-type DC-DC conversion circuit, and the single-ended flyback-type DC-DC conversion circuit outputs multiple paths of isolation power supplies (200) to supply power to the micro control unit (MCU), the inverter circuit and the driving circuit at a later stage. The influence of an instantaneous overcurrent or a voltage fluctuation on multiple paths of isolation power supplies is not large, such that the stability and reliability of the control over an IGBT/MOS switch tube are ensured.
