摘要
为改善逆变器输出波形质量,采用复合控制策略提高逆变器动态响应能力,消除稳态误差。采用瞬时均流法将逆变单元并联,减小模块间环流,提高供电系统输出功率容量和冗余供电能力。在两台1 kW逆变器上进行了实验验证。结果表明单台逆变器输出波形质量高,并联运行时并联模块工作一致,实现了冗余供电。
To improve the quality of output wave, a multiple control strategy is proposed to enhance dynamic response ability and eliminate steady-state error.Instantaneous current sharing method is used to lower circle current between inverter modules to improve power density and redundant power supply ability of power supply system.Experiments are done on two 1 kW inverters.The results show output wave quality is high.Parallelled modules work efficiently and redundant power supply is achieved.
