本文的目的是研究带电容输出滤波器的全桥三元LCC谐振功率变换器的性能。重点研究了变工作频率脉宽调制下的工作。对LCC功率变换器的工作模式进行了计算，并利用归一化图给出了各模式的边界。此外，还评估了降低开关损耗的最佳操作模式。rpi配置对提高逆变器效率的优点进行了分析。除分析研究外，还介绍了实验结果。
The purpose of this paper is to study the performance of a full-bridge three element LCC resonant power converter with a capacitive output filter. The study focuses on the operation under pulsewidth modulation with variable operation frequency. The operation modes of the LCC power converter are evaluated and their boundaries are given by means of normalised diagrams. Furthermore, optimal operation modes with reduced switching losses are evaluated. The advantages of an RPI-configuration for improved inverter efficiency is carried out. Apart from analytical investigations, experimental results are also presented.
