摘　　要：本文分析了全桥逆变器实现交流电流源的原理及设计过程。重点分析了在感性负载下全桥逆变电流源的各个工作模式,通过分析可见,在感性负裁下,该逆变器具有低的谐波含量、软开关等优点。对控制环节设计过程及其体参数选择也做了相应的分析。仿真和实验结果显示了该电流源具有的良好性能。In this paper,a full bridge pulse-width-modulated（ PWM）inverter topology is presented for ac current source. The operation stages of the full bridge inverter operating in an inductive load are particularly analyzed in this paper. The detailed analysis shows that the proposed inverter has very low harmonic distortion, near-zero switching losses. A design procedure is illustrated as well. Simulation and experimental results are presented to prove the performance of the proposed inverter.
