The front stage uses the single-voltage-mode control strategy and the back stage uses the three states discretepulse modulation hysteresis current control strategy.
前级采用电压单环调制方式,后级采用三态滞环离散脉冲调制电流滞环跟踪控制技术。

In accordance with the characteristics that resonant DC link inverter should adopt discretepulse modulation, we propose a novel method of soft SPWM waveform synthesis.
