1. 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, the first STC module including:
an output current (OC) measuring circuit configured to measure a value of a first output current generated by the first STC module;
a digital interface configured to transfer a value of a minimum output current provided by the plurality of STC modules;
a dead time (DT) adjustor configured to compare the value of the first output current with the value of the minimum output current provided by the plurality of STC modules, the DT adjustor configured to adjust a dead time in response to the value of the first output current being greater than the value of the minimum output current; and
a current share (CS) circuit configured to transmit, via the digital interface, 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.
