Motor Drive System

The Z-source inverter has overcome the limitation of the conventional voltage source inverter and current source inverter and provides a new option for motor drive system. The Z-source inverter has the unique ability of boosting the voltage of the dc source, which has advantages in the motor drive system for electric vehicles where the voltage of the onboard battery is usually lower. Firstly, this paper analyses the speed characteristic of permanent magnet brushless dc motor. Then operation principles and the control method are described and an effective and convenient strategy for generating PWM pluses with shoot-through states based on TMS320F2812 DSP is introduced. At last, the results of this experiment are presented and verify the correctness of the model.
