Abstract

A power converter includes a power module, a feedback module, and a control module. The power module is used for converting an input voltage into an output voltage. The feedback module is electrically connected with the power module for generating a feedback voltage according to the output voltage. The control module is electrically connected with the feedback module and the power module for comparing a reference duty cycle value with a duty cycle, generating a variable reference voltage according to the comparison between the reference duty cycle value and the duty cycle, comparing the variable reference voltage with the feedback voltage, and adjusting the duty cycle according to the comparison between the variable reference voltage and the feedback voltage.
