System Of Input Current Sharing For Compact Architecture In A Power Converter

A modular power converter, comprising:

• at least one pair of power conversion sections, wherein each pair of power conversion sections includes:
• a first power conversion section including an input operative to receive a first voltage having a first magnitude and a first frequency and an output operative to deliver a second voltage having a second magnitude and a second frequency, and
• a second power conversion section including an input operative to receive the first voltage and an output operative to deliver the second voltage;
• a mutual choke, wherein the mutual choke includes:
• a first winding electrically connected between a power source and the first power conversion section, and
• a second winding electrically connected between the power source and the second power conversion section, wherein the first and second windings are electrically connected such that a first current in the first winding flows in an opposite direction than a second current in the second winding;
• a current sensor operative to generate a signal corresponding to an amplitude of current provided to at least one of the first power conversion section and the second power conversion section;
• and
• a controller operative to receive the signal from the current sensor and to generate a first set of control signals for the first power conversion section and a second set of control signals for the second power conversion section responsive to the signal from the current sensor.
