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。

Abstract: 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 DClink 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 “twoamplitude” control technology for resonant DClink, which improves the output performance of inverter. The comparison result also verifies the superiority of PWM control scheme with voltage and current doubleloop feedback.
Key words: twoamplitude control; resonant DCLink; inverter; pulse width modulation (PWM); discrete pulse modulation (DPM)
