Abstract

This paper proposed a DSP controlled 2 kW PFC converter with a novel sampling algorithm which can greatly improve switching noise immunity in almost all average current control power supplies. Based on the newly developed DSP chip TMS320F240, a 2 kW PFC stage designed as the front-end of a frequency-variable air-conditioner is implemented. The novel sampling algorithm shows great advantages when the switch operates in the range above 30 kHz
