PWM Current Programmed Control Technique via Non-inverting Boost-Buck Converter Control for Unity Power Factor

This paper presents a referenced voltage control method for PWM generation. This PWM is controlled with a PWM current programmed method for switching the operation of a Non-inverting Boost-Buck converter to improve the power quality in a system that transfers from an AC power source to a DC load. This proposed method uses an electronic circuit for generating the suitable referenced voltage for each DC load change. The simulation shows that the system operates with a good performance for this method. The AC current source is nearly sinusoidal and the power system has a unity power factor.
