Abstract:
1. A power conversion system, comprising: a power converter configured to receive an input voltage, convert the input voltage to an output voltage, and provide the output voltage to a load; a closed loop compensator configured to receive the output voltage and a reference voltage, the closed loop compensator configured to transmit an error signal indicative of a difference between the output voltage and the reference voltage; a pulse width modulator configured to receive the error signal and modulate a control signal with the error signal to control the output voltage, the pulse width modulator configured to transmit the control signal to the power converter; and logic configured to receive the error signal and to measure a frequency of the error signal, the logic further configured to adjust a parameter of the closed loop compensator based on the measured frequency of the error signal, wherein the parameter is a gain of the closed loop compensator, wherein the power converter has a switching frequency, and wherein the logic is further configured to increase the gain of the closed loop compensator if the measured frequency of the error signal is within a specified range of the switching frequency.
