Abstract

A quiet motor speed controller is disclosed which varies an amplitude of an AC voltage signal provided from an AC source to drive an AC motor. The controller includes a first impedance in series connection between the source and the motor. A second impedance is electrically connectable with the first impedance in accordance with settings of a switch such that the total impedance interposed between the source and the load is varied by switching. The first and second impedances are substantially defined by first and second capacitive values, preferably including resistive elements to limit current flow at charging and discharging.
