To address power quality issues in the residential split-phase distribution systems, a novel residential power router (RPR) is proposed in this paper. It consists of a dual-half bridge (DHB) converter and a split-phase inverter. The DHB provides the galvanic isolation and bidirectional power flow channel for the distributed generation terminal. The split-phase inverter can work as the active power filter, the reactive power compensator, and balance the power of two phases. The power balancing mode is critical to a residential microgrid, especially when the utility grid is not accessible. A proportional quasi-resonance and resonance (PQRR) controller is adopted to eliminate the steadystate error for harmonics compensation. Simulation and experimental results are presented in this paper to validate the feasibility and effectiveness of the proposed RPR for residential applications.more » « less
