Abstract :
This paper describes a new method to reduce the output ripple induced by AC power line disturbances for high power, high precision DC power supply applications. The authors use the feedforward signal from the power line and adjust the adaptive gain through the output voltage ripple. This technique is carried out by an analog circuit which has the advantages of low cost and reduced space requirement
