Abstract

This paper introduces a new control technique for power factor correction in ac-dc converters. It has the advantages of conventional hysteresis control strategy and the prominent characteristics PWM control, since the limits of the hysteresis band can be adjusted to provide fixed switching frequency. The operating principles, theoretical analysis and results regarding a single-phase boost converter are presented to validate the proposal.
