Modeling, dynamic analysis and digital control design of a new current auto zero master-less current shared 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 modeled and bench current loop frequency response results.
