Abstract In order to solve the DC-link voltage control problem of the series hybrid active 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 series hybrid active power filter are verified by both the simulation and experiment results.
