Abstract: An inverter circuit for generating an AC signal from a DC input is described herein. The inverter comprises a primary inverter for generating a first portion of a signal, the primary inverter using switches that when actuated efficiently produce the first portion of the signal, the first portion of the signal being an approximation of a sine wave, the approximation of the sine wave having an error component; a secondary inverter for generating a second portion of the signal, the secondary inverter using switches to produce a waveform that that attenuates the error component of the first portion of the signal; and combining means such as a transformer which combine the first and second portions of the generated signal to produce a substantially improved approximation of a sine wave.

Abstract: 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.
