Embodiment Construction

[0025] The present invention provides a method for realizing the conduction electromagnetic interference experiment platform of the electric vehicle motor drive system. The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings, taking the 20kW three-phase AC motor of the electric vehicle as the experimental object.

[0026] Step 1: The power supply 2 converts the alternating current of the grid 1 into 288V direct current and supplies it to the motor controller 5, and the motor controller 5 inverts the direct current into alternating current and supplies power to the 20kW permanent magnet synchronous motor 6. The motor control signal 14 is a motor speed control signal, and the load device 7 is a 30kW dynamometer. By adjusting the motor speed control signal and the dynamometer, the motor 6 is controlled in a stable working state.

[0027] The second step: as attached figure 2 As shown, the test equipment 13 is ...

Description

technical field [0001] The invention relates to a conduction electromagnetic interference experiment platform of an electric vehicle motor drive system, which is used for electromagnetic compatibility testing of the electric vehicle motor drive system. Background technique [0002] The standard "GB / T 18655-2010 Limits and Measurement Methods of Radio Disturbance Characteristics of Vehicles, Ships and Internal Combustion Engines Used to Protect Vehicle Receivers" limits the electromagnetic field emission intensity of electric vehicles. The AC motor drive system for electric vehicles is controlled by inverter Inverter power circuit, control circuit, chassis, radiator, cables and other parts, among which the main components of the inverter power circuit are power modules or components, such as PIM or IGBT. These power modules, such as IGBT, are in high-speed on-off mode during operation, and high-frequency dv / dt will be formed between its collector and emitter, thereby generati...
