摘要
This paper proposes a new quasi-current-resonant dc-link ac/ac pulsewidth modulation (PWM) converter. Because the proposed circuit realizes zero-current switching for all switching devices using the current resonance, the switching losses and EMI are decreasing. The proposed circuit with thyristors also realizes high-frequency switching. The output currents and voltages are precisely controlled to be sinusoidal wave using PWM technique in the computer simulation and the experiment.
