This paper presents a novel prototype of the utility AC power interfaced soft-switching sinewave pulse modulated inverter using the high-frequency flyback transformer for the small seale distnbuted renewable energy power conditioner The pioposed sinewave power conditioner circuit with a high-frequency isolation link has a function of electrical isolation, which is more cost-effective and reliable for the small-scale distributed renewal energy utilization system from a safety point of view The discontinuous conduction mode (DCM) operation of the high-frequency flyback transformer is adopted to establish a simple and low-cost circuit configuration and control scheme For the simplicity, the circuit operating principle is described on the basis of the modified conventional full bridge inverter, which is the typical conventional high-frequency full-bridge inverter employing the high frequency flyback transformer to enable the effective function of the electrical isolation Then, the new circuit topology of the utility-interfaced soft-switching sinewave pulse modulated inverter using IGBTs is proposed The proposed circuit topology si additionally composed of the auxiliary power regenerating snubber circuits, which are also mathematically analyzed for the purpose of the parameter design settings Finally, the performance of the proposed inverter is evaluated on the basis of computcr-aid simulation It is noted that the sinewave pulse modulated output current of the inverter is synchronous to the AC main voltage
