Claim:
1. A power converter, comprising: a switching circuit; a power conversion circuit configured to receive an input voltage via the switching circuit and convert the input voltage into an output voltage; an input voltage sense circuit configured to detect the input voltage and generate an input voltage sense signal; an output sense circuit configured to: a reference voltage module configured to generate a reference voltage based on the input voltage sense signal provided by the input voltage sense circuit such that the reference voltage is proportional to the input voltage; and a first operational amplifier configured to generate a first comparison signal based on a difference between the output voltage sense signal and the reference voltage; a second operational amplifier configured to generate a second comparison signal based on a difference between the output current sense signal and the first comparison signal, the second comparison signal being provided as a feedback signal; and a PWM controller configured and programmed:
