Abstract

Abstract

En 中文
An improved control strategy of standard power factor preregulators (PFP's) is proposed, which allows fast output voltage response while maintaining a high power factor. This is obtained by compensating for the intrinsic low-frequency output voltage ripple, thus allowing a higher bandwidth of the output voltage control loop. This method does not require additional sensing, but only a multiplier and simple analog circuitry, and it works well with a universal input voltage range. Experimental tests on a boost converter with average current control confirm the validity of the approach.
