要約(英語): This study proposes a novel active power decoupling (APD) control method focusing on the power generation characteristics of photovoltaic (PV) arrays. Numerous studies have been conducted on the APD method for achieving a long lifetime of a residential PV power generation system. The APD method reduces the power pulsation, which contains twice the utility frequency caused by a single-phase PV inverter. Compared with the passive power decoupling method using electrolytic capacitors, the APD method incurs power conversion loss due to the increase in passive components and power devices. Many studies have considered the efficiency improvement of the APD method, however most of them focus on the power conversion loss of the APD circuit. It is necessary to consider the power conversion efficiency of the power conditioner and the power generation efficiency of the PV array collectively to improve the efficiency of the PV system. Therefore, in this study, a compensation power control for APD circuit focusing on the power generation characteristics of the PV array is proposed, and the validity of the proposed APD control was verified by evaluating the efficiency based on real-time simulation and experimental results of a 1kW power conditioner.
