Flyback Converter as Auxiliary Power Supply for Low-cost Single-phase Motor System; IEEE student contest - Future Energy Challenge 2005

Innovations in motors and motor drive systems, that could replace "universal motor" brush machines in residential applications, bring adjustable speed motor system costing less than US $40 for a 500W unit. The goal of this paper is to present use of flyback converter for auxiliary power supply in a proposed integrated electrical drive. Paper also shows the comparison of buck and flyback converters, with calculations and schemes
