Abstract

Disclosed is an apparatus and method for controlling a single-phase induction motor, particularly, an apparatus and method for controlling a single-phase induction motor, capable of rendering the motor strong to variation of an input voltage, protecting the motor from an over-voltage, and starting or driving the motor stably and efficiently even in a low voltage condition, wherein a simplified circuit including switches can be constructed without use of a PTC thermistor or an overload protector and a current phase can be controlled, thereby improving starting capability.
