摘要

针对串联混合型有源电力滤波器直流母线电压控制问题，提出了一种新的不依赖于串联变压器端口电压检测的控制策略，由逆变器生成大小固定的有功电流，从而使串联变压器承受的基波电压保持稳定。仿真和实验表明，该控制策略可以较好地控制串联混合型有源电力滤波器直流母线电压。%In order to solve the DC-link voltage control problem ot tlae series nyDnu acuve power filter, a new control strategy is proposed in this paper. This control strategy is independent of the detection of the primary winding port voltage of the series transformer. The inverter generates fixed active current, so that the fundamental voltage loss of the series transformer may remain stable. Finally, the good control effects of the DC-link voltage of the both the simulation and experiment results. series hybrid active power filter are verified by
