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. The development of a modified triangular signal for the PWM control is introduced in this paper. The performance of the proposed modified PWM control scheme is verified by using computer simulation and experimental results
