다국어 초록 (Multilingual Abstract)

This paper presents a novel prototype of the utility-interfaced si- nusoidal pulse width modulated (SPWM) inverter using the high-frequency fiyback transformer for the small-scale solar photo- voltaic power conditioner (lkW - 4kW) The proposed SPWM power conditioner circuit with a high-frequency link has a function of electrical isolation, which is vital for solar photovoltaic power conditioner systems with the viewpoint of safety and convenience The discontinuous conduction mode (DCM) operation of the fly. back transformer is also maintained to simplify the topology of the inverter circuit and control scheme first, the operating principle of the proposed circuit is described for the understanding of the circuit parameters establishment. Then, the digitally constructed SPWM control scheme is presented The proposed circuit is verified by the computer Simulation and the prototype experiment<br/>
