基于MSP430的高功率因数程控开关电源设计

High Power Fator and Programable Swith Power Design Based on MSP430

采用有源功率因数校正整流控制芯片UCC28019构成电压外环和电流内环的双闭环控制,设计出了一种高功率因数校正(APFC)电源。系统采用MSP430F149单片机进行监控,完成输出电压的可调及相关测量参数显示功能,以及其它外围器件实现系统功率因数、输出电压、电流的实时测量、人机交互、输出过流保护等功能。

A higher power factor correction （APFC）power is designed adopt active power hetor correction rectifier control chip UCC28019 constitute double - loop control of the voltage loop and inner current loop. The system uses the MSP430F149 to monitor the completion of the display features of adjustable output vohage and measurement pa- rameters, as well as other peripheral devices to achieve real - time measurement of the system power factor, output voltage, current, human - computer interaction, and output overeurrent protection function.
