Multiple mode universal power source

A method for controlling three-phase electrical power, the power having a polarity and power frequency, the method comprising:

• providing three-phase electrical power from a wye-connected power source, each phase of electrical power being offset from the other phases of electrical power by phase angles of 2π/3 radians;
• reversing the polarity of each phase of electrical power at a first frequency;
• applying the reversing polarity electrical power through an at least two-winding transformer having a set of primary terminals and a set of secondary terminals for each phase of electrical power, the primary terminals being configured to receive the reversing polarity electrical power, the secondary terminals being configured to induce an electrical power having a voltage and a current;
• generating a phase-angle-modulated first signal at the first frequency to correspond with each phase of the three-phase power;
• reversing the polarity of each phase of the induced electrical power according to the generated phase-angle-modulated first signal;
• and
• applying the induced electrical power to a load.

A universal mode power controller, the controller comprising:

• a primary clock configured to generate a clock signal;
• a secondary clock configured to phase-shift the clock signal to generate a phase-shifted clock signal;
• a primary gating array, the primary gating array having primary input terminals and primary output terminals and configured to periodically reverse power received at the primary input terminals and presented at the primary output terminals according to the clock signal;
• a transformer having at least two windings and having primary transformer terminals and secondary transformer terminals, the primary transformer terminals being electrically connected to the primary output terminals;
• and
• a secondary gating array, the secondary gating array having secondary input terminals and secondary output terminals and configured to periodically reverse power received at the secondary input terminals and presented at the secondary output terminals according to the phase-shifted clock signal, the secondary input terminals being electrically connected to the secondary transformer terminals.
