The primary side of a transformer for an electric device is constructed as a star-connection or a delta-connection, and the secondary side is constructed so that each phase produces two single-phase AC supplies in such a manner that one circuit of the three single-phase AC supplies produces a DC output, and another circuit inverts one phase using a P-N-P semiconductor and an N-P-N semiconductor, and this is combined with the other two phases to produce a single phase AC supply. |
