Abstract :
A switched mode power supply (SMPS) with full digital control has many advantages over analog or mixed-signal implementation. This paper presents a digital controlled SMPS consisting of an AC-DC power factor correction converter and a phase-shifted full-bridge DC-DC converter. Digital algorithm of PFC control, system design of digital PFC and PSFB (phase shifted full bridge) part, PWM strategy for phase-shifted control are discussed. A 500 W prototype has been built and tested under different conditions
