Abstract :
A simulation of DSP-based control of paralleled boost PFC with minimized current sensors is presented. The proposed scheme operates properly with only one current sensor at the supply side. Output ripple voltage is computed to increase system bandwidth while supply current is still sinusoidal operation. Feed forward current control is proposed so that tracking ability will be improved. The 3-module PFC at the rate of 3 kW is simulated by MATLAB/Simulink to verify the proposed techniques
