摘要

本文提出了一种用于三相电机驱动的直流轨道并联谐振零电压转换电压源逆变器电路(DC-rail PR ZVT VSI)。在该电路中，所有开关都在零电压开关(ZVS)或零电流开关(ZCS)下接通或关断，没有高电压和电流应力。所需的谐振元件和辅助开关的额定功率很小。本文详细介绍了该控制方案的理论分析、辅助开关和整流元件的选择原则以及所提出电路的控制策略。最后，通过实验结果验证了该电路的有效性和效率。讨论了实际应用中的一些问题。

A novel DC-rail parallel resonant ZVT VSI for three-phase AC motor drive

This paper proposes a novel circuit of DC-rail parallel resonant zero voltage transition voltage-source inverter (DC-Rail PR ZVT VSI) for three-phase motor drive. In this circuit all switches are turned on or turned off under the zero voltage switching (ZVS) or zero current switching (ZCS) without high stress of voltage and current. Power ratings of the resonant components and auxiliary switches required are small. The control scheme is simple and less dependant on load current This paper gives details of the theoretical analysis, the rules of selecting the auxiliary switches and the commutation components and the control strategy of the proposed circuits. Finally, the validity and the efficiency of the circuit are tested and verified by experiment results. Some questions in practical application are discussed.
