Abstract :
A low-end MCU base power factor corrector (PFC) is proposed in this paper. Due to green power issue, PFC is more important, but need an extra controller to achieve. However, in most electric equipments and appliances, the MCU is used to accomplish key functions or handle user interface. The structure and control strategy proposed in this paper is based on the rest calculation resource of the MCU build in appliances. The simulation results show the method is workable, the quantization effect caused by build in ADC and PWM timer of MCU are also considered in simulation stage. The experimental results are present in the paper to show the scheme is workable.
