摘要

负载调节是逆变器的一项关键性能指标。因此，本文对串并联输出逆变器的负载调节进行了分析。阐述了其工作原理和控制策略。详细分析了不同参数对串联和并联输出模式下负载调节的影响。最后，通过l-kVA串并联输出双降压半桥逆变器进行了仿真和实验验证。仿真和实验结果表明，当两种输出模式的输出功率相同且串联输出电压为并联输出电压的2倍时，逆变器在两种输出模式下的负载调节效果良好且相同。

Analysis of Load Regulation for Series and Parallel Output Inverters

Load regulation is a key performance indicator of inverters. Therefore, analysis of load regulation for series and parallel output inverters is proposed. The operating principle and control strategy are illustrated. Influence of different parameters on load regulation at series and parallel output modes is analyzed in detail. Finally, simulation and experimental results verify the analysis by a l-kVA series and parallel output dual-buck half-bridge inverter. The simulation and experimental results demonstrate that the load regulation of the inverter at both output modes is good and same when the output power at both modes is same and the output voltage at series output mode is twice that at parallel output mode.
