| 20100290261 | Machine, Computer Program Product And Method For Implementing An Improved Efficiency And Reduced Harmonic Distortion Inverter - A machine, computer program product and method for implementing an improved inverter circuit that converts, with high efficiency, direct-current electrical power (DC) to alternating-current electrical power (AC) with low signal distortion is described herein. The machine to convert a DC input into an AC output comprises a first inverter comprising a plurality of first transistors, at least some of the first transistors receiving the DC signal, the first inverter generating a first inversion signal, the first inversion signal having an error component; a second inverter comprising a plurality of second transistors, the plurality of the second transistors connected to at least one of the first transistors, the second inverter generating a second inversion signal; a combining circuit connected to the first inverter and second inverter, combining circuit producing the AC output; and a computer defining a waveform synthesizer, the waveform synthesizer having an A/D converter for receiving a sample signal from the combining circuit and converting the sample signal into a plurality of digital data points; a non-transient computer memory having instructions stored thereon and a computer processor for executing the instructions, the instructions performing a process of computing an error between the sample signal and an ideal sine waveform and a process of correcting the error. | 11-18-2010 |
