| 摘 要： | 基于分布式控制的逆变器并联系统由2台采用电压电流双闭环反馈控制的逆变器模块组成.由一种分布在各单元中的平均电路对各逆变模块的电流给定进行综合后生成各模块共享的电流给定信号,实现瞬时均流.采用TMS320F240型DSP芯片实现数字锁相同步,实现并联系统的热插拔功能.仿真和实验结果表明,该控制方法具有很好的动静态均流性能.

| Abstract: | The distribution controlled inverter parallel system is composed of two inverter modules based on the volt-age and current double closed-loop feedback control.Instantaneous current sharing is realized through the shared current reference which is generated from the current reference of every inverter by specially designed averaging circuits distribut-ed in the inverter modules in parallel.TMS320F240 DSP is used to realize the digital Phase Locked Loop(PLL) and real-ize the hot-swap function of the parallel system.Simulative and experimental results indicate that excellent fast transient response and current sharing capabilities are obtained through the control method presented in this paper. |
