Digital PWM pulse delay control of multiple output DC-DC converter

With the continuous development of faster and cheaper microprocessors the field of applications for digital control is constantly expanding. In this paper, Digital PWM Pulse Delay multiple output dc-dc converters are presented. The main objective of this paper is to regulate the all the outputs with reduced control signals and without post regulation. Operation analysis and power block design are shown. Finally, simulation and experimental results for a PWM Pulse Delay three outputs isolated converter are shown.
