摘要
在基于负载电流前馈解耦的正弦波逆变器多环控制策略中,负载电流前馈作用的延迟直接影响着系统的性能。文章在负载电流的检测回路中引入了微分补偿环节,使逆变器性能得到进一步提高;为验证所设计的具有微分补偿多环控制系统的正确性,构建了一台基于DSP TMS320F2407A的1 kV.A单相正弦波逆变器样机。
In the multiple-loop control strategy for sinusoidal inverters based on load current feedforward, delay of the feedforward directly impacts the system's performance. To overcome this drawback, a differential element is adopted in the test of load current, and then the inverter's performance is improved markedly. To test and verify the control system with differential compensation, a 1 kV · A prototype of single-phase sinusoidal inverters based on DSP TMS320F2407A is built.
