Abstract
Provided is a safety power window controlling method including an operation in which a ripple current detector detects a ripple current by removing high-frequency noise from an output current signal of a four-pole stator motor; an operation in which an amplifier receives a ripple current as a first input signal, receives a reference voltage as a second input signal, and outputs an amplified current signal obtained by amplifying the first input signal to a level of the reference voltage; and detecting the amplified current signal output by the amplifier as a valid signal by using at least two preset reference values.
