摘要： A coil-driving apparatus of an electro magnetic contactor is disclosed, which replaces the main units in an analog scheme with those in a digital scheme using a PWM controller of low power consumption to reduce the number of the analog components, minimize power consumption, and controls a constant voltage that flows on the coil by receiving the feedback current flowing on the coil, whereby error and defect generation rates are reduced, and deterioration and burning of components are prevented.
