The control system of electric vehicle motor is generally composed of motor, power inverter, sensor and Controller

Electric vehicle controller.

The electric vehicle motor control system should choose a more suitable synchronization system according to the complexity of its control algorithm. Many simple ones have replacement microcontroller controllers, and complex ones can use DSP controllers. The latest motor-driven dedicated chips can meet the motor control needs of some auxiliary systems. For electric vehicle motor controllers, DSP processors are generally suitable.

The control circuit mainly includes the following parts: control chip and its driving system, AD sampling system, power module and its driving system, hardware protection system, position detection system, bus support capacitor, etc.

The main power circuit uses the inverter full bridge as shown in Figure 4-32. The main power switching device is IG-BT. Under high-current and high-frequency switching conditions, the stray inductance from the electrolytic capacitor to the power switch module affects the temperature of the power circuit and the peak voltage on the module affects the series connection. Therefore, the alternating bus substrate is used to make the stray inductance of the circuit small To adapt to the characteristics of the control system low voltage, high current work.
