Translated Title
Voltage PI+current predictive controlled bridgeless dual-Boost PFC converter
Translated Abstract
To solve the problems of conventional double loop PI control and hysteresis current control of the du-al-boost PFC converter,in the input current distortion,fast dynamic response and high power factor. An optimization algorithm based on traditional voltage PI combined with predictive current inner loop control is proposed. The algo-rithm solved the problems of slow dynamic response and waveform distortion of double loop PI control,and low pow-er factor of the voltage PI combined with current hysteresis control. Realization of digital control of dual-boost PFC converter with high power factor,fast dynamic response and lower harmonic pollution. The experimental results of the dual-boost PFC converter showed that the total harmonic distortion was 4 . 2% and the power factor was 0 . 998 .
