1. A solid state transformer, comprising an input stage operatively coupled to an isolation stage;
- wherein said input stage converts a high voltage, single phase AC input voltage to a plurality of (N) unisolated DC output voltages, each said unisolated DC output voltage being at a voltage level which is less than the voltage level of said AC input voltage, and wherein each of said unisolated DC output voltages is separately isolated in said isolation stage.

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.
