Application note
Single-phase induction motor drive
for refrigerator compressor application (formerly AN1354)

Introduction
Up to now, refrigerator compressors have been controlled by electromechanical switches
(thermostat or even electronically controlled relays). This choice was driven by the high
inrush current that can appear when the rotor is stalled. Furthermore, electromechanical
relays were advantageous because they were less sensitive to line voltage disturbances.
Today, new semiconductor devices feature ov
