Abstract

A solid state transformer having an input stage operatively coupled to an isolation stage. The input stage converts a high voltage, single phase AC input voltage to a plurality of unisolated DC output voltages. Each unisolated DC output voltage is at a voltage level which is less than the voltage level of the AC input voltage and each of the unisolated DC output voltages is separately isolated in the isolation stage.
