提出了一种级联型复合电流质量调节装置主电路拓扑,与传统拓扑相对比,采用了双PWM变换技术.PWM整流器为装置提供了稳定的直流电压,实现输入功率因数近似为1,同时实现了直流电压与输出电流的解耦控制.逆变侧采用谐波与无功统一补偿的控制策略,并采用输出电流直接PI闭环反馈控制,保证良好的电流跟踪效果.最后设计了一套基于DSP+FPGA控制的低压实验原理样机,验证了所提出的主电路拓扑及控制策略的可行性和有效性.

A main circuit topology of cascaded recombination current quality compensator is proposed.Compared to the conventional topology,it uses double PWM converter technology.PWM rectifier provides a stable DC voltage for the device,implements input power factor approximately 1 and also achieves decoupling control of DC voltage and output current.The inverter side uses harmonic and reactive power unified compensation control strategy and adopts PI closed-100p feedback control of output current directly to ensure good current tracking results.Finally.a low-pressure experimental prototype is designed based on DSP and FPGA,it verifies the feasibility and effectiveness of this control strategy and main circuit topology.
