Research on Parallel Inverter

根据变频器并联运行的原理,设计了一种变频器并联运行的方案。该方案控制简单,容易实现,环流抑制效果好。根据设计的方案建立了变频器并联的仿真模型和实验平台,结果表明变频器在并联运行中工作稳定,环流小,验证了方案的有效性。

A strategy of parallel inverter was designed based on the principle of parallel inverter. The strategy was simple, easy, and effeetively restrained circulating current. The simulation model and experimental platform was established according to the strategy. The result showed that the inverter had a stable working condition, low circulating current, so it proved the effectiveness of the strategy.
