Abstract
A power invertor system for converting a direct current (DC) input voltage to an alternate current (AC) output voltage with an output analog wave-shape. The power invertor system includes a digitized sequencing circuit for receiving a sequence of clock signals for generating a digitized up-down sequence as a function of the dock signals. The power invertor system further includes a digitized wave signal generating circuit employing the DC input voltage and the digitized up-down sequence to generate a digitized wave signal approximating the analog wave shape of the AC output voltage. The power invertor system further includes a filtering and smoothing circuit for filtering and smoothing the digitized wave signal to generate the AC output voltage with the analog wave shape.
