Patent ID: 7053591

Claim:
A power conversion device comprising: a means for sensing an output current of an output drive device; a means for sensing an output voltage, said sensed output current and said sensed output voltage configured to form a plurality of sensed output signals; a means for producing a plurality of voltage reference sources; a means for comparing said plurality of sensed output signals with said plurality of voltage reference sources to produce a plurality of modifying signals, said means for comparing coupled to an output of said means for sensing an output current and coupled to an output of said means for sensing an output voltage; a means for combining said plurality of modifying signals, said means for combining coupled to an output of said plurality of means for comparing; a means for producing an output drive control signal from said combined plurality of modifying signals, said means for producing an output coupled to an output of said means for combining; and a means for producing a regulated output drive level from said output drive control signal, said output drive control signal configured as a feedback of said sensed output current and said sensed output voltage to regulate said output drive level of said output drive device, said sensed output current configured as a first component of said feedback compared with a first one of said plurality of voltage reference sources to produce a first one of said plurality of modifying signals, said sensed output voltage configured as a second component of said feedback compared with a second one of said plurality of voltage reference sources, the first one of said plurality of modifying signals and the second one of said plurality of modifying signals combine to produce said output drive control signal.
