電流不連続モードを用いたフライバックコンバータの単相パワーデカップリング法

抄録

This paper discusses a power decoupling method using fly-back converter with discontinuous current mode (DCM) for PV micro-inverters. The proposed converter consists of a fly-back converter, voltage source inverter (VSI), and small capacitor. The proposed method does not require any additional component or complicated control for power decoupling. From the experimental result, the second-order harmonics of the PV input current is reduced by 97%, in comparison with that in the current continuous mode (CCM).
