本文提出了一种采用高频反激式变压器环节的实用互动式电压源型正弦脉冲调制功率逆变器样机。由于功率处理系统的安全性，所提出的用于太阳能光伏发电和小型燃料电池的功率调节电路具有隔离功能，这对于小型分布式可再生能源调节和处理系统来说更具成本效益和接受性。该功率处理变换电路采用断续电流模式(DCM)，实现了一种简单的电路拓扑和脉冲调制控制方案。在仿真评价和理论考虑的基础上，对其工作原理进行了描述。仿真结果表明，该逆变器输出的正弦波形和单位功率因数电流与电网中的主电压同步。本文提出并讨论了高频联动正弦波脉冲调制逆变器的软开关拓扑。

This paper presents a novel prototype of the utility-interactive voltage source type sinewave pulse modulated power inverter using a high-frequency flyback transformer link The proposed power conditioner circuit for the solar photovoltaic generation and small scale fuel cell has an isolation function due to the safety of the power processing system, which is more cost effective and acceptable for the small-scale distributed renewal energy conditioning and processing systems. The discontinuous current mode(DCM) of this power processing conversion circuit is applied to implement a simple circuit topology and pulse modulated control scheme. Its operation principle is described on the basis of simulation evaluations and theoretical considerations. The simulation results obtained herein prove that the proposed inverter outputs with sinusoidal waveforms and unity power factor currents are synchronized to the main voltage in utility power source grid. In this paper, the soft switching topology of high-frequency linked sinewave pulse modulation inverter is proposed and discussed.
