Types of PWM-PD multiple output DC/DC converters

In this paper, the different types of multiple output DC/DC converters based on the PWM-PD control are presented. These converters work at fixed switching frequency and they are characterized by having a bigger number of fully regulated outputs than number of controlled switches. Basically, this new family of converters can be divided in three groups: converters without transformer, with transformer and without post-regulation, and with transformer and with post-regulation. Finally, the experimental results for a converter fully regulated, with three outputs and two MOSFETs are shown.
