Uncertainty mathematical models of power converters

Declarative Representation of Uncertainty in Mathematical Models

An important aspect of multi-scale modelling is the ability to represent mathematical models in forms that can be exchanged between modellers and tools. While the development of languages like CellML and SBML have provided standardised declarative exchange formats for mathematical models, independent of the algorithm to be applied to the model, to date these standards have not provided a clear ...

Synthesis of Averaged Circuit Models for Switched Power Converters

Averaged circuit models for switching power converters are useful for purposes of analysis and obtaining engineering intuition into the operation of these switched circuits. This paper develops averaged circuit models for switching converters using an in-place averaging method. The method proceeds in a systematic fashion by determining appropriate averaged circuit elements that are consistent w...

SiC-BASED POWER CONVERTERS

The advantages that silicon carbide (SiC) based power electronic devices offer are being realized by using prototype or experimental devices in many different power applications ranging from medium voltage to high voltage or for high temperature or high switching frequency applications. The main advantages of using SiC-based devices are reduced thermal management requirements and smaller passiv...

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...
