【Abstract】 This paper presents a new interleaved power factor correction system based on DSP chip TMS320F28027 and the average current dual-loop control PFC algorithm. System debugging results show that compared with the traditional PFC control with analog circuit,the system has faster dynamic response and greater ability of power supply disturbances capability. The system can effectively reduce the input voltage and current ripple,and decrease the stress of power electronics,simplify the design of the PFC converter and improve the stability of the interleaved power factor correction system.更多还原
