1. An apparatus comprising:
a power source configured to generate a multiphase alternating current (AC) input signal;
a primary transformer circuit including a plurality of primary coils, the primary transformer circuit configured to receive the multiphase AC input signal from the power source, the primary transformer circuit configured to generate and provide a plurality of first multiphase AC output signals to an electrical device or electrical system based on the multiphase AC input signal received from the power source; and
a delta secondary transformer circuit configured to magnetically couple to the primary transformer circuit, the delta secondary transformer circuit configured to generate and provide a plurality of second multiphase AC output signals to a rectifier based at least on the multiphase AC input signal received from the power source, the delta secondary transformer circuit including:
a first plurality of secondary coils;
a first plurality of nodes coupled to the first plurality of secondary coils; and
a second plurality of secondary coils configured to magnetically couple to the plurality of primary coils, wherein each coil of the second plurality of secondary coils is physically coupled to a respective node of the first plurality of nodes.
