Dynamic power converter and method thereof
First Claim
1. An alternating current (AC) to direct current (DC) power converter comprising:
- a plurality of switches controllable by a processor;
an input configured to receive an input AC waveform having an input power; and
an output configured to output a controllable DC supply voltage having an output power;
wherein the processor is configured to;
calculate a power conversion efficiency based on a calculated value of the output power and a calculated value of the input power;
control a first portion of the plurality of switches to adjust an operating condition, wherein the processor tracks an effect of the adjusted operating condition on the calculated power conversion efficiency, and wherein the processor controls a second portion of the plurality of switches to improve the calculated power conversion efficiency based on the tracked effect of the adjusted operating condition on the calculated power conversion efficiency; and
control a third portion of the plurality of switches to selectively harvest different portions of the input AC waveform based on a change in the operating condition.

Abstract
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.
