Title:
CIRCUIT FOR REDUCING ELECTROMAGNETIC INTERFERENCE, DISTRIBUTION BOX, NEW ENERGY VEHICLE, AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/165587
Kind Code:
A1
Abstract:
The present application relates to the field of new energy vehicles, and in particular, to a circuit for reducing electromagnetic interference, a distribution box, a new energy vehicle, and a method therefor. The circuit comprises: an identifying module, used to identify electromagnetic interference of a vehicle-mounted electric appliance; a control signal generation module, used to determine a control signal according to the electromagnetic interference of the vehicle-mounted electric appliance; a control module, used to generate a control current to be input to a magnetic ring according to the control signal; and a magnetic ring, connected between a power supply of a vehicle and the vehicle-mounted electric appliance, and generating a magnetic flux change according to the control current, so as to counteract the electromagnetic interference of the vehicle-mounted electric appliance. According to the present application, electromagnetic interference generated by a vehicle-mounted high-voltage electric appliance is accurately filtered out by controlling a current input to a magnetic ring without changing the size of the magnetic ring, thereby improving the efficiency of the vehicle-mounted device and improving the electromagnetic interference characteristics of the entire electric vehicle.
