The paper evolves a mechanism for improving the input power factor of an AC-DC-DC change system. It involves the process of shaping the input current wave to phase align with the input supply through a process of error benefit. The methodology includes cohesive formulation to arrive at nearly unity power factor and enjoy the etiquettes of output voltage regulation.
The theory relieve to subscribe the benefits for the entire range of operating loads. It eliminates the use of passive components and fortifies the principles of pulse width modulation (PWM) for realizing the change in duty cycle. The MA TLAB based simulation results mediate the viability of the planned approach and exhibit its rightness for use in real world applications.

A single stage power factor correction strategy has been planned for full bridge diode rectifier fed boost converter to support a 400W, lA DC load. The suitability of boost converter for power factor correction has been decorated by the elimination of input capacitor filter and low output ripple factor. The develop control design has been efficiently organize to correct the power factor in addition providing good voltage regulation.
The transient work has been represent to up-heave the strength of the control structure with an able output regulation and effective harmonic elimination. The control plan has been feed to standardize the THD level of the system that prevents the adverse effects of harmonics being injected in the grid.
The exclusion of additional passive components and interleaving arrangement has been promote to reduce the size thus making it more adaptive to low cost compact electronic applications with high standards .
