Analysis and prediction of regulation in a multiple-outputcurrent-mode controlled DC-to-DC converter

A technique is developed for predicting the closed-loop steady state output voltage regulation of a multiple-output current-mode controlled converter. The proposed model accounts for the current loop, the voltage loop, and the integrator in the compensation scheme. This method allows tradeoffs with respect to regulation between different components or feedback configurations to be evaluated during the design of a converter. Experimental verification on a three-output current-mode controlled push-pull converter with single output voltage feedback is provided
