摘　　要：新颖的全桥式高频环节逆变器,由高频逆变桥、高频变压器、周波变换器以及输入、输出滤波器构成,包括全桥全波式和全桥桥式拓扑。该文首次对双极性、单极性移相控制全桥式高频环节逆变器的控制策略、原理特性、关键电路参数设计准则和原理试验等进行了深入的比较研究,获得了重要研究结论。相对于双极性移相控制时,单极性移相控制高频环节逆变器获得了更优的综合性能。移相控制全桥式高频环节逆变器,在中大功率DC/AC变换场合具有重要的工程应用价值。The novel full-bridge mode inverters with high frequency link are constituted of high frequency inverter bridge, high frequency transformer, cycloconverter, input and output filters. The converters have the full bridge-full wave and the full bridge-full bridge mode circuit topologies. The control strategy, principle characteristics, design criteria of the key circuit parameters and principle test of two kinds of phase-shifted controlled inverters are deeply and comparatively investigated firstly in this paper, and important conclusions are obtained. Compared with the bi-polarity phase-shifted controlled inverters, the uni-polarity phase-shifted controlled inverters have better, comprehensive performances. The phase- shifted controlled full-bridge mode inverters have important engineering application value in medium or large power inversion fields.
