This paper presents a buck-boost PWM power inverter and its application for residential photovoltaic system. The PWM power inverter is realized by driving a inverter constructed with a high frequency buck-boost chopper in the discontinuous conduction mode (DCM). Photovoltaic system with the power inverter has the following advantages: (1) The power generated by the photovoltaic array can be transfered to the load and the utility line under any array voltage, (2) Isolation between the photovoltaic array and the utility line is performed by a small high frequency reactor operating as energy storage element, (3) There is no need of a reactor to link the utility line, (4) Unity power factor operation is provided, (5) So the system configuration is very simple. The input-output characteristics of the system is analyzed. As the result, the ripple component of the array current and the power flow between the interface and the utility line are derived, and verified experimentally.
