Development of a novel Zero-voltage and Zero-current-Switching PWM DC/DC Full-Bridge Converters controller Liu xin-qiao, Zhang Ji-lai, Tan li, Ling Jun-jie (College of E&I Engineering, Jiangsu University, Zhenjiang Jiangsu 212013 China) Abstract: A novel ZVZCS converter is proposed which uses a coupled output inductor. The principle of the novel converter is simply analyzed. The design process UC3875 as the core controller , the drive circuit and the parameter choice are analyzed. Lastly, simulation and experimental results are presented ,which have showed the controller design and the parameter choice were reasonable.
