Abstract
A synthesized sinewave dc/ac converter of low-level discrete voltage sources (cells) is analyzed with respect to the load current, voltage, and harmonics of an inductive load. With this approach, it is possible to design a highly efficient inverter with low harmonic content. The high efficiency is obtained by using switching in place of a transformer. The low content of harmonics is a result of proper switching times. The number of cells connected in parallel in each module of the inverter is determined by the criterion of equal charge transfer of each cell. The design of the inverter may be accomplished with the Motorola MC68HC11 microcomputer.
