Design and implementation of single-phase boost PFC converter

Abstract EN

In this paper, a single-phase boost type ac-dc converter with power factor correction (PFC) technique is designed and implemented.

A current mode control at a constant switching frequency is used as a control strategy for PFC converter.

The PFC converter is a single-stage single-switch boost converter that uses a current shaping technique to reshape the non-sinusoidal input current drawn by the bulky capacitor in the conventional rectifier.

This technique should provide an input current with almost free-harmonics, comply with the IEC61000-3-2 limits, and a system operates with near unity power factor.

The other function of the boost converter that should be accomplished is to provide a regulated DC output voltage.

The complete designed system is simulated in MATLAB / SIMULINK and a hardware prototype has been built using analog devices.

Simulation results and experimental results are presented to validate the proposed system.
