摘　　要：在大功率照明领域,以高压钠灯和金卤灯为代表的HID灯依然是主流的选择。在大功率HID灯电子镇流器中,逆变环节是一个重要的环节。针对常用的LCC谐振逆变电路的效率提升问题,提出了一种新型的LCLC谐振逆变电路。在保证ZVS的条件下,通过参数设计和开关频率设定,可以实现近似的零电流开关。文中给出了无源参数的设计方法及实验结果。In the field of high-power lighting, High Intensity Discharge （HID）, with the representative of HPSL （high pressure sodium lamp） and metal halide, remains a main choice. Inverter circuit plays an important role in the design of high-power electronic ballast. A novel topology of LCLC resonant inverter circuit was proposed in order to solve the issue of efficiency lifting. By setting the switching frequency and parameters, the goal of ZCS could be achieved approximately, while under the condition of ZVS. The experimental results and ways of passive parameters design were presented finally.
