Abstract :
The proposed analog-based modified PWM control scheme for the DC-AC inverter can eliminate the low order harmonic components caused by the nonconstant DC voltage source. A simple high power factor full-bridge rectifier with the valley-fill filter is selected to realize the nonconstant DC voltage source. Operation modes of the valley fill filter are included in the paper. The performance of the proposed modified PWM control scheme is verified by computer simulation and experimental results
