“…To overcome this limitation, several novel SHPF topologies have been proposed to simultaneously take into account the harmonic currents and the reactive power [10][11][12][13][14]. In [10][11][12], additional passive components, such as capacitors, inductors, or coupling transformers, were inserted into the typical SHPF to improve harmonic current and reactive power compensation capability. However, these approaches required additional hardware, which degraded the costeffective advantage of the SHPF.…”

-This paper introduces a novel topology and an effective control strategy for a shunt hybrid power filter (SHPF) to simultaneously compensate harmonic currents and reactive power. The proposed SHPF topology is composed of an LC passive filter tuned to the 7 th harmonic frequency and a small-rated active filter connected in parallel with the inductor L pf of the LC passive filter. Together with the SHPF topology, we also propose a control strategy, which consists of a proportional-integral (PI) controller for DC-link voltage regulation and a PI plus repetitive current controller, in order to compensate both the harmonic current and the reactive power without the need for additional hardware. Thanks to the effectiveness of the proposed control scheme, the supply current is sufficiently compensated to be sinusoidal and in-phase with the supply voltage, regardless of the distorted and phase lagging of the load current. The effectiveness of the proposed SHPF topology and control strategy is verified by simulated and experimental results.
