Abstract
The power converters employing the provided methods and controllers are proposed. The controller includes: a signal preprocessor for generating a current signal according to a sensed current of the transformer, an integrator electrically connected to the signal preprocessor for integrating the current signal and offering an integrated signal, a synthesizer electrically connected to the integrator for receiving and synthesizing the integrated signal and a slope compensation signal to generate a synthesized signal, an operational amplifier of a control loop for generating an amplified error signal, and a PWM comparator electrically connected to the operational amplifier and the synthesizer for comparing the amplified error signal and the synthesized signal and generating a PWM signal to turn on and off a switch of the transformer accordingly.
