Experimental evaluation of active power factor correction techniques in a single‐phase AC‐DC boost converter

Abstract

Summary The increasing need to improve power quality with the reduction of the harmonic content of current and voltage waveforms has been intensively analyzed in several studies, thus motivating the proposal of many high power factor rectifiers based on the classic converters such as boost and buck‐boost. Moreover, distinct control techniques have also been proposed due to the commercial availability of integrated circuits (ICs) dedicated to impose sinusoidal input currents in switch‐mode power supplies (SMPSs). The boost converter operating in continuous conduction mode (CCM) is by far the most traditional choice for this purpose due to circuit simplicity and low electromagnetic interference (EMI) levels. Within this context, this work analyzes some of the most important control techniques used in power factor correction (PFC). The performance of a single‐phase boost converter using peak current mode control (PCMC), average current mode control (ACMC), and one cycle control (OCC) is evaluated experimentally in detail. A comprehensive analysis of key aspects such as the input current waveform and respective harmonic content, dc output voltage, and dynamic response of the converter is also presented.

A cost‐effective switched inductor‐based bridgeless Sepic converter for PQ enrichment in power solutions

“…Later on, buck-boost topologies were coming into an extent for wave shaping with improved PQ performances. [10][11][12] Yet, these structures incur conduction losses due to the presence of DBR, so as to minimize these conduction losses, several bridgeless topologies were derived and are listed in literatures. [13][14][15][16][17] Though conduction losses were minimal, the boost and buck topologies are seldom used in view of its limited voltage range capabilities on both input and output.…”
