Abstract
Disclosed is a method of acquiring input and output voltage information by employing a pulse width modulation (PWM) controller, which is in collocation with an input power processing unit, a primary inductor, a switch element, a current-sensing resistor, an output rectifier, and an output filter for converting an alternating current input power into an rectified input power and an output power, and the output power supplies an external load. A current-sensing signal is specifically disposed and applied to calculation of the input voltage and output voltage of the rectified input power when the switch element is turned on and off, respectively. Thus, no resistive voltage divider is needed, and power consumption at no load is greatly improved.
