摘要

本文提出了一种准方波直流链路(QSWDCL)变换器，改进了现有拓扑结构的性能。所提出的电路提供零直流链路电压陷波，在此期间逆变器开关受到影响，并对PWM逆变器施加最小的直流母线电压应力。给出了简单的设计条件。仿真和实验结果验证了所提拓扑的有效性。

An improved quasi-square-wave DC-link converter

This paper proposes a quasi-square-wave DC link (QSWDCL) converter, which improves the performance of an existing topology. The proposed circuit provides zero-DC-link voltage notches, during which the inverter switching is effected, and imposes a minimum DC bus voltage stress to the PWM inverter. Simple design conditions are offered. Simulated and experimental results demonstrate the validity of the proposed topologies.
