대용량 ZVS FB DC/DC 컨버터에 있어서 Digital-To-Phase Shift PWM 발생회로

With the advent of the high-speed microprocessor and DSP, the possibility of executing a control strategy m digital domain has become a reality. By the use of the DSP and microprocessor controller, many high power converters such as especially inverter and motor drive system may be enhanced resulting m the improved robustness to EMI, the ability to communicate the operating conditions and the ease of adjusting the control parameters, But, the digital controller using DSP or microprocessor is not applied m the high frequency switching power supplies, espe챠ally full bridge DC/DC converter So, this paper presents the method and realization of designing a digital-to-phase shift PWM circuit for full digital controlled full bridge DC/DC converter with zero voltage switching, The operating principles, simulation and experimental results will be presented,
