Abstract

A voltage sourced inverter system includes an inverter for coupling to a DC power source and an interphase transformer bank coupled to the inverter. The inverter includes a number of poles for providing discretely displaced voltage waveforms to the interphase transformer bank. A main transformer operably coupled to the interphase transformer bank transforms power therefrom into an AC power output. The interphase transformer bank may be a singular stage or a hierarchial arrangement of plural interphase transformers which combine the discretely displaced voltage waveforms to reduce selected harmonic components therefrom. The inverter may provide notched waveforms to remove additional selected harmonics from the discretely displaced voltage waveforms. A method of inverting DC power into AC power with reduced selected harmonic components is also disclosed.
