ABSTRACT:
A power supply control apparatus and method are provided. The apparatus includes a controller outputting a first pulse width modulation (PWM) signal for supplying an electric power and a second PWM signal to be compared to the first PWM signal, a first PWM signal input unit converting the second PWM signal to a direct current (DC) signal, a second PWM signal input unit receiving the converted second PWM signal, a comparator comparing the first PWM signal and the converted second PWM signal, a switching unit generating a waveform having a voltage according to the comparison result of the comparator, a transformer transforming the voltage of the generated pulse waveform according to the switching result of the switching unit and a rectifier and voltage divider for rectifying and voltage-dividing the transforming result of the transformer, wherein the controller adjusts the second PWM signal by receiving the rectifying and voltage-dividing result of the rectifier & voltage divider.
