Abstract

This paper addresses the dynamic analysis of paralleled power converter systems employing nonlinear load-sharing control techniques. The first section of the paper analyzes nonlinear load-sharing control techniques which are linearizable about a constant operating point. The second section of the paper analyzes the dynamics of the widely-used UC3907 control scheme for an important special case. In both cases, the analyses are validated against experimental results
