Classification: CPC H | IPC H

Claim 11:
12. A power supply, comprising:
a output;
a source comprising a control signal input, and a return side communicating with the output, wherein the source is configured to output an output voltage as measured from the return side to the output based on a control signal received at the control signal input and an amplifier output signal received at the return side;
a voltage divider configured to produce a measurement signal proportionally attenuated from the output voltage;
an error amplifier comprising a feedback input, a setting input, and an amplifier output, wherein the error amplifier is configured to receive the measurement signal from the voltage divider at the feedback input, receive a digital-to-analog converter (DAC) output signal at the setting input, produce the amplifier output signal based on the measurement signal and the DAC output signal, and output the amplifier output signal from the amplifier output to the return side; and
a digital processor configured to receive the measurement signal converted to an analog-to-digital converter (ADC) data signal, receive the amplifier output signal from the error amplifier, receive a digital set-point input signal, and produce a first digital DAC data signal and a second digital DAC data signal based on the ADC data signal, the amplifier output signal, and the digital set-point input signal, wherein the digital set-point input signal corresponds to a set-point voltage value of the output voltage that is to be outputted at the output.
