abstract = {To address the harmonic pollution caused by nonlinear loads, a single-tuned hybrid active power filter (HAPF) with asymmetric topology is proposed, which consists of a three-phase voltage converter and a two-phase LC passive filter. By analyzing the operating principle and characteristics of the new topology, a filtering equivalent circuit is designed. By analyzing the working principle and characteristics of the new topology, a filter equivalent circuit is constructed. The two-phase current with passive filter is used to construct the control quantity of asymmetric third-phase current, which can effectively suppress the three phase harmonic current of the power grid and control the DC-link voltage of the filter. The DC-link voltage is stabilized by Proportional Integral (PI) . The topology circuit and control strategy are tested by conducting simulations and experiments, and the experimental results validate the feasibility of the proposed topology and control scheme.}
