Soft-switching AC module inverter with flyback transformer for photovoltaic power system | Modułowy przekształtnik AC z transformatorem typy flyback w systemie fotowoltaicznym

This paper presents an AC module inverter for photovoltaic (PV) power system. The PV inverter employs a Buck-Boost converter on the DC side and a flyback inverter on the AC side. Based on capacitive idling (CI) techniques and peak current control method, the proposed inverter shows low current distortion, high power factor, small power decoupling capacitor and soft-switching operation. Analysis and experimental results are provided to demonstrate these excellent features.
