Patent ID: 7218541

Claim:
An inverter for providing power to a load, the inverter comprising: a first stage component operable to receive a first voltage input and a first control input to generate a first voltage output higher than the first voltage input, wherein the first control input is indicative of the power provided to the load, wherein the first voltage output varies in response to a change in the first voltage input by a predefined function; a second stage component operable to receive the first voltage output and a second control input to generate the power, wherein the second control input is indicative of the power provided to the load; a controller component operable to receive a feedback input indicative of the power required by the load and generate the first and second control inputs to the first and second stage components, respectively; and the first control input provided to adjust a duty cycle of the first stage component to vary the first voltage output in response to power required by the load, and the second control input, generated by the controller component, is indicative of power provided to the load.
