基于开关周期平均模型的PWM变流器的改进型SVPWM控制
The SVPWM Control of PWM Converter Based on the Switching Cycle Average Model
The average space state mathematic model of the PWM converter as a rectifier and as an inverter is established.The mathematic model in synchronous rotating coordinate is also obtained.The implementation principle of the improved SVPWM control strategy is introduced.Compared with traditional SVPWM control strategy,the improved SVPWM control strategy can reduce the switching losses and improve system efficiency.The simulation waveforms are obtained and they agree with the theory analysis.The proposed mathematic models and the improved SVPWM control strategy are correct and have any reference value to the other related power circuit topology devices.
