摘　　要：选取了两种逆变器的脉宽调制(PWM)控制方案,并对其在有源箝位谐振直流环节逆变器(ACRDCLI)中的适用性进行了仿真分析,并与典型的离散脉冲调制(DPM)控制方案进行了对比研究。实验结果表明,采用"双幅"控制技术的ACRDCLI PWM控制方案,可以得到离散输出频谱,并改善了逆变输出性能,验证了电压电流双环反馈的PWM控制方案的优越性。Two kinds of pulse width modulation （PWM） control schemes for inverter were selected. Simulation analysis was made to verify the applicability of the two schemes on actively clamped resonant DC-link inverter （ ACRDCLI）. Comparison between the PWM control schemes and conventional discrete pulse modulation （DPM） scheme was given. A discrete output spectrum is obtained by combining the PWM scheme for inverter with the ＂ two-amplitude＂ control technology for resonant DC-link, which improves the output performance of inverter. The comparison result also verifies the superiority of PWM control scheme with voltage and current double-loop feedback.
