Multiple Input Single Output DC-DC Converter with Equal Load Sharing on the Multiple Inputs

A method of balancing a direct current load across a plurality of direct current power sources comprising:

• receiving a plurality of direct current inputs to a corresponding plurality of inputs to a multiple input single output converter, wherein each one of the plurality of inputs corresponds to and are coupled to one of a plurality of DC to DC converter modules;
• comparing an output current of each one of the plurality of DC to DC converter modules to a reference current;
• adjusting the output current of at least one of the plurality of DC to DC converter modules including:
• increasing the current output of the at least one of the plurality of DC to DC converter modules when the output current of the at least one of the plurality of DC to DC converter modules is less than the reference current;
• decreasing the current output of the at least one of the plurality of DC to DC converter modules when the output current of the at least one of the plurality of DC to DC converter modules is greater than the reference current;
• and
• making no change to the current output of the at least one of the plurality of DC to DC converter modules when the output current of the at least one of the plurality DC to DC converter modules equal to the reference current;
• combining the output current of the plurality of DC to DC converter modules in a single output current;
• and
• outputting the single output current.
