Abstract

This paper describes an adjustable speed drive (ASD) for residential applications such as compressors and fans in heat pumps, air conditioners, and refrigerators. The ASD uses only a four-diode rectifier and a six-transistor six-diode inverter and does not require a source-frequency filter inductor or capacitor, Motor speed is adjusted with source-frequency phase control eliminating the switching loss and electromagnetic interference caused by the more-commonly used high-frequency pulse-width modulation (PWM). A full-load operating point with reasonable power factor and source-current distortion is found using a parametric analysis
