Abstract

A system for generating an alternating current waveform from a direct current source is provided. The system comprises a plurality of inverter-transformer stages, each comprising at least one single phase inverter, which in turn comprises a plurality of switching arrangements, and at least one single phase transformer, each transformer having a primary side and a secondary side, the secondary side of the transformer/s being coupled in series to a load, each of the transformers comprising a secondary binary weighted coil so as to produce a predetermined voltage over the secondary side of each of the transformers. The switching arrangements including a plurality of switches, the switching arrangements being coupled to the primary side of each of the transformers so as to selectively connect the primary side of each transformer to the direct current source. An alternating current waveform is generated across the load having a voltage level corresponding to the sum of the weighting of said secondary binary weighted coils on each of said single-phase transformers.
