Abstract
An apparatus such as a power converter includes: an input interface operative to receive an output voltage generated by a power converter stage; compensation circuitry including switch circuitry and a flying capacitor to derive a compensation current from the output voltage received from the power converter stage; and an output interface operative to supply the compensation current to the power converter stage. Implementation of the compensation circuitry and corresponding generation of the compensation current as discussed herein reduces a respective ripple associated with the output voltage.
Claims20
An apparatus comprising:
- an input interface operative to receive an output voltage generated by a power converter stage;
- compensation circuitry including switch circuitry and a flying capacitor to derive a compensation current from the output voltage received from the power converter stage;
- and
- an output interface operative to supply the compensation current to the power converter stage, the compensation current operative to reduce a magnitude of ripple associated with the output voltage.
A method comprising:
- via an input interface, receiving an output voltage from a power converter stage;
- via compensation circuitry including switch circuitry and a flying capacitor, producing a compensation current from the output voltage received from the power converter stage;
- and
- via an output interface, supplying the compensation current to the power converter stage, the compensation current reducing a magnitude of ripple associated with the output voltage.
