A Simple Unity Power Factor Motor Drive for Home Appliances
This paper describes a low-power Switched Reluctance motor drive for home appliances featuring close to unity power factor and low cost. The proposed drive includes a compact Power Factor Controller input stage based on a quasiresonant boost topology. The converter structure is suitable for integration and allows one to develop an inexpensive chip implementing all the main functions required by such a drive. Experimental results on a prototype are presented to evaluate the efficiency of the proposed drive.
