Systems and methods for high power DC/DC conversion using voltage converter cells

A method for voltage conversion, the method comprising:

• generating a plurality of phase-shift modulation signals;
• interleaving the phase-shift modulation signals to provide interleaved phase-shift modulation signals;
• and
• controlling a plurality of voltage converter cells using the interleaved phase-shift modulation signals to convert an input electrical current at an input voltage to an output electrical current at an output voltage, wherein at least one voltage converter cell of the plurality of voltage converter cells comprises:
• a transformer comprising a primary side and a secondary side;
• a full-bridge voltage converter connected in parallel to the primary side;
• and
• a plurality of center-tapped rectifiers connected in series to the secondary side, wherein at least one group of outputs of the voltage converter cells are coupled in series via the plurality of center-tapped rectifiers.
