Abstract: A DC solenoid coil current controller includes a rectifier, pulse width modulator, and power driver. The rectifier inputs an alternating current signal and a direct current signal, and outputs a rectified signal using at least one of the alternating current signal and the direct current signal. The pulse width modulator outputs a pulse width modulated signal in response to the rectified signal. The power driver controls a DC solenoid coil using the pulse width modulated signal, thereby enabling a direct current DC solenoid coil to be controlled in response to the alternating current signal. A method of controlling current to a DC solenoid coil is also disclosed.
