An Application of a Ripple Current Cancellation Technique to a Boost Power Factor Correction Circuit for Electronic Ballasts

摘要

In this article we provide an analysis, design, and implementation of a universal input 150-Watt boost power factor correction converter with a ripple current cancellation circuit for lighting industry. A simulation and experimental bench test model of the 150-Watt boost power factor converter with the ripple current cancellation circuit is presented. The results obtained from the simulation and experimental model are presented. The EMI results of the ripple current cancellation circuit are compared with the traditional filtering method used for the EMI suppression on the 150-Watt boost power factor correction converter. Advantages of the proposed ripple current cancelation circuit are discussed.
