Non-regulated power converter with current sharing control

A power converter, comprising:

• a plurality of switching tank converter (STC) modules configured to be connected in parallel and to a load, the plurality of STC modules not including a voltage feedback loop, the plurality of STC modules including a first STC module and a second STC module;
• and
• a digital interface connected to the plurality of STC modules, the digital configured to share a value of a minimum output current with each STC module, the value of the minimum output current being a minimum of a first output current generated by the first STC module and a second output current generated by the second STC module,
• the first STC module configured to increase a dead time in response to a value of the first output current being greater than the value of the minimum output current.

A method for controlling a power converter, the method comprising:

• measuring, by a first switching tank converter (STC) module connected in parallel with a second STC module, a value of a first output current generated by the first STC module, the first STC module or the second STC module not including a voltage feedback loop;
• receiving, by a digital interface, a value of a minimum output current provided by the first STC module and the second STC module;
• comparing, by the first STC module, the value of the first output current with the value of the minimum output current;
• increasing, by the first STC module, a dead time associated with STC cycles of the first STC module in response to the value of the first output current being greater than the value of the minimum output current;
• and
• updating, by the first STC module, the value of the minimum output current to be the value of the first output current in response to the value of the first output current being less than the value of the minimum output current.
