Abstract

In this paper, a small-signal model is developed for the PWM-pulse delay (PD) multiple output DC/DC power converters working in the continuous conduction mode. The control-block is presented and the closed-loop circuit performances, such as the line, load and cross regulation, are obtained analytically. Finally, experimental results for a PWM-PD converter, with three fully regulated outputs and with a transformer, are shown
