Poster Presentation

LT-Spice is a powerful simulation language that is specifically optimized for modeling Switch Mode Power conversion. It is not limited to small numbers of nodes and freely available. We are presenting several examples of simulations for popular electronic power factor correction circuits that improve the input power factor of AC Power Supplies by active wave-shaping of the AC input current and...

29. An Investigation into the Next Generation of High Density, Ultra High Voltage, Power Supplies

Mr Russell Frost (University of Southampton)

Power Electronics, Power Supplies, Prime Power, Rotating Machines, and Energy Converters

Oral Presentation

There is growing interest, from both industry and academia, for a DC power supply capable of outputting 2MW at 1MV. Ideally, the geographic footprint of such a power supply would be as small as possible, meaning that the design will need a high power density. If a fault, such as a short circuit, were to occur in a system that stored a lot of energy the results could be catastrophic. For this...

43. Overview of the Lockheed Martin Compact Fusion Reactor (CFR) Pulsed Power Systems

Power Electronics, Power Supplies, Prime Power, Rotating Machines, and Energy Converters

Oral Presentation

The Lockheed Martin Compact Fusion Reactor (CFR) Program endeavors to quickly develop a compact, 100 MWe class fusion power plant with favorable commercial economics and military utility. The CFR uses a diamagnetic, high beta, magnetically encapsulated, linear ring cusp plasma confinement scheme. One advantage of the CFR is how the size lends itself to an iterative, rapid prototyping design...

162. The Benefits of Using Cascode GaN Power Devices in a DC-DC Bidirectional Buck-Boost Converter

Mr Salah S. Alharbi (University of Denver )

Power Electronics, Power Supplies, Prime Power, Rotating Machines, and Energy Converters

Oral Presentation

Due to global concerns over climate change and the depletion of fossil fuels, the worldwide interest in renewable energy sources, such as photovoltaic (PV) and wind, is increased significantly for electricity generation. Grid-connected PV and wind energy conversion systems with battery energy storage are considered to be the fastest developing clean energy technologies because of their...

198. Modeling of Inverters for Fuel Cells for Grid-Tied and Islanding mode with smooth transitions

Michael Giesselmann (Texas Tech University)

06/06/2018, 11:15

Power Electronics, Power Supplies, Prime Power, Rotating Machines, and Energy Converters

Oral Presentation

We are reporting on models for a group of inverters that can feed real and reactive power into a utility grid in Grid-Tied mode and is able to transition smoothly transition to islanded mode. In grid tied mode, the inverters are operating in D-Q mode and inject controllable amounts of real and reactive power into the grid. In islanded mode the inverters are grid forming and share power using...
