Design considerations for single-stage isolated power-factor-corrected power supplies with fast regulation of the output voltage

Abstract

The paper introduces a new family of single-stage isolated power-factor-corrected power supplies with fast regulation of the output voltage, and discusses the most-important design issues, including all of the following: storage-capacitor voltage, dual-range and wide-range operation, device RMS currents, and line harmonic currents. In addition to the theoretical analyses, experimental data are also provided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
