Abstract

A reduced-cost reduced-loss adjustable speed drive for residential applications such as compressors and fans in heat pumps, air conditioners, and refrigerators is described. Line-frequency phase control regulates motor speed without the switching loss and electromagnetic interference problems caused by high-frequency pulse-width modulation. Motor equivalent circuit elements function as a line-frequency filter. Reasonably undistorted line current and high power factor at full load are achieved by careful system design
