Monolithic Magnetic Modules for DC-DC Power Converters

DC-DC Power Converters

Dc-dc power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude (and possibly polarity...

Monolithic Integration of GaN Transistors for Higher Efficiency and Power Density in DC-DC Converters

Power converters are constantly trending towards higher output power, higher efficiency, and higher power density. To provide improved performance better power devices are required. For silicon (Si) power devices, the gains in performance have slowed as the technology has matured and approaches its theoretical limits [1]. Gallium nitride (GaN) devices have emerged as a possible replacement for ...

Novel DC/DC Converters For High-Power Distributed Power Systems

Designing Power Line Filters for DC-DC Converters

A method for designing power line filters for SMPS is presented. The practical design work is optimized, by excluding the nonviable combinations of filter components. The designer can choose among the theoretically viable combinations, to try practical designs. The theoretical calculations are based on chain parameters. As an illustration of the method a single stage π-filter for a buck convert...

A Robust Controller For DC-DC Switched Mode Power Converters

Power converters often consist of linear circuits that are switched between two configurations. Even though each of the configurations is linear, the overall behavior of the circuit is nonlinear. DC-DC switched mode power converters constitute simple but yet efficient means of DC power regulation [ 1,2]. The analysis and control of such a circuit is fairly complicated. Different methods have be...
