Abstract

With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. International Standards in the area of compliance of a product’s AC mains current harmonics have forced that new power supply design must include the power factor correction at the front end. The new trend in Power Supply is towards the digital control. This paper discusses the design of a controller for Power Factor Correction (PFC). A microcontroller based PFC design is proposed and design issues are discussed. PFC is simulated using MATLAB and results are reported. Interface requirement between the power converter and microcontroller are discussed.
