CPC H02M 3/1582 (2013.01) [H02M 1/0025 (2021.05); H02M 1/0003 (2021.05)] | 17 Claims |
1. A circuit, comprising:
an alternating current (AC) divider coupled between a first power converter input and a ground terminal, the AC divider having a first feedback output and configured to receive a first signal at the first power converter input;
a direct current (DC) divider coupled between a second power converter input and the ground terminal, the DC divider having a second feedback output and configured to receive a second signal at the second power converter input, in which the second signal has a lower voltage than the first signal;
a controller having a feedback input, a reference input, and a power converter control output, the feedback input coupled to the first and second feedback outputs, and the controller configured to:
receive a feedback signal at the feedback input;
receive a particular reference signal at the reference input; and
provide a control signal at the power converter control output responsive to a difference between the particular reference signal and the feedback signal; and
an amplifier having a first input coupled to the power converter, a second input coupled to the power converter control output of the controller, and an output coupled to the power converter.
