Tubes à rayons X Résumé : Multiduty ratio (MDR) modulation, a novel modulation technique for switching dc-dc converters, is proposed and studied in this paper. MDR modulation technique achieves output voltage regulation by generating a control pulse train made up of control pulses with different duty ratios. MDR control needs only comparators, triggers, and some simple logic devices without an error amplifier and its corresponding compensation circuit; thus, the MDR modulation scheme is easy to realize, benefits with great robustness, and offers great transient performance. The principle and the operation of the MDR modulation scheme are introduced; simulation and experimental results are presented to show that an MDR-controlled converter has much better transient performance than a traditional pulsewidth modulation converter and has much lower output voltage ripple than a pulse-regulation converter.
