Power factor correction using parallel boost converter

Abstract

The increased use of power electronic devices has declined the power quality in terms of introduction of harmonics and lowering of power factor.This is due to their non-linear nature of operation. Hence,power factor correction (PFC) is the need of the hour.This thesis informs about the various PFC methods and focusses on PFC using parallel boost converter in particular. A design of the PFC using parallel boost converter employing average mode control in done and the results so obtained are compared with that of a single boost converter and a rectifier circuit without any PFC circuit.
