摘要

介绍了一种5kw实用交互式高性能串联谐振逆变器的设计。逆变器工作在一个不可听的频率范围(20 kHz-100 kHz)和准谐振模式。对逆变器的分析研究结果表明，在这种工作模式下，逆变器的输出特性为电流源型，与交流电源的输出电压无关。逆变器在软换相模式下使用开通可控COMFET开关，不需要缓冲电路。该变换器结合了高频工作的优点(重量轻，无功滤波器小，无低频变压器)和使用允许使用零电流关断开关的谐振链路。本文介绍了在容量为2.5千瓦的实验室样机上获得的一些实验和仿真结果。

A 5 kW utility-interactive inverter operating at high frequency and using zero current turn off COMFET switches

The design of a 5 kW utility-interactive high-performance series resonant inverter is described. The inverter operates in an inaudible frequency range (20 kHz-100 kHz) and in the quasi-resonant mode. The results of an analytical study of the inverter show that, in this mode of operation, the inverter output characteristics are of the current-source type independent of the output voltage of the AC utility. The inverter uses turn-on controllable COMFET switches in the soft commutation mode and does not require snubber circuits. This converter combines the advantages of working at high frequency (less weight, small reactive filters, and absence of low-frequency transformer) and of using resonant links that allow the use of zero-current turn-off switches. Some of the experimental and simulation results obtained on a 2.5 kW-capacity laboratory prototype are presented.<>
