摘　　要：研究了一种高频链反激逆变器拓扑及其工作在电感电流连续模式下的控制方案。电路不存在可能出现的正激通道,因而占空比可大于0.5,得到了较宽范围的输出电压。通过采用同步整流,提高了整机效率。给出了控制方案和主要参数设计,并进行了实验验证。实验表明,电路结构简单,运行可靠,易于模块化,且稳态和动态特性良好,负载适应性好,具有四象限运行能力。A novel high frequency link flyback inverter which works in the continuous conduction mode （CCM） is presented.Wider output voltage domain was realized by varying the duty ratio over 0.5 because there was no forward pathway in the circuit.The efficiency had been improved by using a synchronous rectification.The control program and the main parameters design with experiment test are presented.The method is proved having simple circuit structure,stable running,good steady-state and dynamic properties, load adaptability and four-quadrant operation capabi＇lity.
