Note: The following application demos are made for VTB PE 1.61

ElectoMagnetic Aircraft Launching System (EMALS)

The charter objective for the VTB program is to provide an infrastructure that supports virtual prototyping of next-generation electric systems for Navy vessels. This includes, but is not limited to the traction systems of an all electric ship. Of the many challenges for electrical engineers one of the more intriguing is the possible requirement on aircraft carriers of the future for an Electromagnetic Aircraft Launching System, (EMALS), a linear motor system to replace existing steam catapults.

Hybrid Electric Vehicle (HEV)

Hybrid Electric Vehicles (HEVs) combine two or more energy conversion technologies (e.g., heat engines, fuel cells, generators, or motors) with one or more energy storage technologies (e.g., fuel, batteries, super capacitors, or flywheels). The combination of conventional and electric propulsion systems offers the possibility of greatly reducing emissions and fuel consumption.

Power Electronic Building Blocks (PEBB)

The VTB project supports development and applications of Power Electronic Building Blocks (PEBBs). PEBBs are solid state components of the next-generation electronic power converters in 3rd generation development. PEBBs will be able to serve in multiple capacities, depending only on how the controller is programmed. A power controller based on PEBB technology might be configured as a DC to AC inverter, a synchronous rectifier, or a motor controller simply by changing the controlling software. PEBBs incorporate arrays of high-power switches, microprocessors and appropriate passive waveshaping components. The VTB supports the PEBB program in three ways:

 1. Advanced PEBB Control Algorithms
2. PEBB Applications
3. PEBB Prototyping

Fuel Cell Plant

The purpose of the fuel cell plant simulation is to design and evaluate system performance and control strategies. With VTB the entire fuel cell system is implemented and evaluated. Including, pump, compressor, regulator, PEM fuel cell stack, power conversion and other auxiliary component, thermal, mechanical, electrical and electrochemical characteristics. By the virtue of the multidisciplinary environment, flexible model generation, co-simulation, and real-time user interaction aspects of VTB, a complete fuel cell system and control topology are verified without the use of costly equipment.
