Sensing and control for improving switched power supplies

摘要

A power converter and a method of operation thereof is disclosed including an input, an output, a sensor unit, a switched power converter, and a processor module. The power converter may convert an input power into an output power. The power converter may sense real-time measurements of the input power and the output power to determine a real-time calculated efficiency. The power converter may chop the input power into sized and positioned portions of the input power based on a plurality of determined operating parameters. The power converter may determine the operating parameters based on the real-time calculated efficiency and on a plurality of other operating factors/conditions.

1. A power converter comprising:
an input configured to receive an input power waveform from an input power source; an output configured to generate a converted power; a sensor unit configured to sense at least one indication of an operating condition; and a switched power converter configured to:
select one or more portions of the input power waveform to satisfy a target operating condition, wherein the selected one or more portions are selected based on the at least one indication of an operating condition; andavoid selecting one or more other portions of the input power waveform to satisfy the target operating condition; andconvert the one or more portions of the input power waveform to the output.
