Abstract

Transformer for an electrical device. Conventionally, in order to convert 3-phase power into single-phase power, a motor generator is used or the 3-phase AC voltages are first converted into DC voltages which are then converted into a single-phase AC voltage. However, this transformer receives 3-phase AC voltages, produces 3 single-phase AC voltages at the secondary side and produces a single-phase AC voltage by combining the phases.
