Claim:
1. A control system for a power converter comprising: a digital reference signal generator configured to: a first proportional-integral (PI) controller coupled to the digital reference signal generator and configured to receive the input voltage reference signal and the input voltage and provide a first PI control signal at a first PI controller output based on the input voltage reference signal and the input voltage; a second PI controller configured to receive a constant output voltage reference signal and an output voltage from the power converter and provide a second PI control signal at a second PI controller output based on the constant output voltage reference signal and the output voltage; and a diode including an anode coupled to the first PI controller output and a cathode coupled to the second PI controller output, wherein the anode of the diode forms a control system output.
