Average modeling, simulation and analysis of a new digital auto zero master-less current share converters

This paper introduces a new modular master-less active control method for current share in digitally controlled DC-DC converters that communicate over single wire bus. Current balance among paralleled converters is achieved with new current error zeroing method. Experimental results show the new scheme exhibiting excellent static and stable dynamic current matching performance. The paper also includes correlated simulated and bench current loop frequency response results.
