Abstract :
This paper presents a research of full digital-controlled AC/DC converter, which consists of single Boost PFC and LLC resonant DC/DC converter. The whole control system structure is proposed to integrate all analog control functions. By digital control, it can reduce the system´s volume and costs, improve characteristics. As a proof of this design, an example of 240W AC/DC converter is given. The experimental results show that the design of AC/DC converter is feasible.
