Switch-mode technology is the common choice for high-efficiency audio power amplifiers. The dynamic nature of real limits achievable continuous output thus reducing efficiency. Based on methods used radio frequency (RF) amplifiers, this article proposes a tracking multilevel supply (TMLPS) in order to improve system A simple prototype designed and tested up 200 W. Measured results show that emp...

Numerical modeling and analysis are effective techniques to assist in the design of high-frequency switching power supplies. Striving for high power densities and higher efficiencies has pushed the operating frequencies up, resulting in new circuit configurations and different component architecture. This paper presents a numerical method that is used to analyze magnetic systems for switching p...

Motivated by the importance of energy storage networks in smart grids, we provide an algorithmic study of the online energy storage management problem in a network setting, the first to the best of our knowledge. Given online power supplies, either entirely renewable supplies or those in combination with traditional supplies, we want to route power from the supplies to demands using storage uni...

Boost power converters have been widely used for Power Factor Correction (PFC) in AC-DC conversions [1] and for power management in battery powered DC-DC conversions [2]. Moving beyond low-power applications, such as cellular phones, smart phones and other portable electronic products, boost converters are being used more and more in medium-power applications. For example, in computing and cons...

Switch mode power supplies as a mass produced article leave room for optimization especially at the voluminous magnetic components. Hereby planar component designs can reduce the overall height of the power supply and give it a more compact design. Since cores are available in standard sizes the optimal winding layout has to be found. Due to increased parasitic capacitance interleaving is not a...

Abstract: For high-speed circuits, on-chip inductance can no longer be ignored. This paper deals with inductance in the presence of multi-layered meshes used for on-chip power supplies. We have shown ways of designing power/ground (p/g) mesh that reduce inductance. Accurate 3-dimensional inductance extraction problem is intractable for large chips. We have demonstrated the feasibility of using ...

The Starshine 3 satellite will carry several power technology demonstrations. Since Starshine 3 is primarily a passive experiment and does not need electrical power to successfully complete its mission, the requirement for a highly reliable power system is greatly reduced. This creates an excellent opportunity to test new power technologies. Several government and commercial interests have team...
