Claim 20:
21. A method of servicing an aircraft, the method comprising:
installing a variable frequency constant voltage generator (VFCVG), the VFCVG configured to generate a multiphase alternating current (AC) input signal;
installing a primary transformer circuit of a transformer on the aircraft, the primary transformer circuit including a plurality of primary coils, the primary transformer circuit configured to receive the multiphase AC input signal from the VFCVG; and
installing a delta secondary transformer circuit of the transformer on the aircraft, the delta secondary transformer circuit configured to generate and provide a multiphase AC output signal to a rectifier based at least on the multiphase AC input signal received from the VFCVG, 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.
