摘要
提出了一种新型的DC/AC逆变器拓扑结构,并分析了其工作原理。它是一个改进的电压馈电串/并联软开关准谐振逆变器,能达到大范围且平稳的输出功率调节、低的开关损耗和成本,在仿真和电子镇流器的实际应用中得到了验证。
A novel DC/AC inverter circuit topology and its operation principle have been proposed. It is a voltage-fed quasi-resonant soft-switching series-parallel inverter that can attain soft-switching operation and regulate its output power continuously over a wide range. The inverter is joined with a boost power-factor correction converter at the input line to make the line current follow naturally the sinusoidal line voltage. Using reverse recovery attribute decreases energy consumption of this new circuit. Additionally, the new inverter can achieve wide range and smoother output power regulation accordingly smoother input power regulation and lower power consuming than the conventional inverter, widening the regulation range as well as high conversion efficiency is attained under soft-switching operation. Despite more electronic components and complex circuit, with the rapid decline of price of semiconductors and ferrite core, electronic ballast production cost has decreased significantly. High performance can bring about economic benefits and great market potential.
