Transformer and method of generating multiple multiphase output signals

A method of operating a transformer, the method comprising:

• receiving, from a variable frequency constant voltage generator (VFCVG), a multiphase alternating current (AC) input signal at the transformer;
• generating, using a primary transformer circuit of the transformer and based on the multiphase AC input signal received from the VFCVG, a first multiphase AC output signal;
• generating, using a secondary transformer circuit of the transformer, a first plurality of signals of a second multiphase AC output signal based at least on the multiphase AC input signal received from the VFCVG;
• generating, using the secondary transformer circuit of the transformer, a second plurality of signals of the second multiphase AC output signal based at least on the multiphase AC input signal received from the VFCVG;
• and
• providing the second multiphase AC output signal to a rectifier.
