Benefits of technology

The patent describes a power distribution unit that includes two solid state power modules, each containing many power controllers. These modules are interchangeable and can be placed in the same chassis. The units can be controlled using a control interface. The technical effects of this invention include high-density power distribution and flexibility in module placement and control.

Problems solved by technology

Applications requiring power distribution often have severe space constraints for power distribution system components.
The limited space available for system components drives the requirement for high density power distribution.
Circuit breaker panels are sized to attempt to fit into the space constrained areas, which are often unavailable during flight and are difficult to access on the ground, in the case of an aircraft.

Embodiment Construction

[0012]Referring to FIG. 1, a power distribution unit is generally schematically illustrated with reference numeral 10. The power distribution unit 10 may be employed in a variety of applications, such as an aircraft or another vehicle (not illustrated), for example. The vehicle includes a plurality of powered vehicle systems 12, 14, 16. The power distribution unit 10 provides power to the powered vehicle systems 12, 14, 16 and is supplied power by a power supply 18.

[0013]The power distribution unit 10 comprises a logic section 20 and a power section 22, with the power section 22 being made up, at least in part, by one or more solid state power modules (SSPMs) 24, each having a plurality of solid state power controllers (SSPCs) 26. The SSPCs 26 employs transistors to provide a switching function and use electronics to provide a circuit breaker function to protect wiring associated with the power vehicle systems 12, 14, 16. The SSPMs 24, based on the composition of SSPCs 26, provide a...

Abstract

A power distribution unit includes a first solid state power module comprising a first plurality of solid state power controllers, where the first solid state power module comprises a first set of power characteristics. Also included is a second solid state power module comprising a second plurality of solid state power controllers. The second solid state power module comprises a second set of power characteristics. Also, the first solid state power module and the second solid state power module are interchangeably coupled to a first location of a common chassis.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 453,249, filed Mar. 16, 2011.BACKGROUND OF THE INVENTION[0002]The present invention relates to power distribution systems, and more particularly to high density power systems and methods of high density power distribution.[0003]Applications requiring power distribution often have severe space constraints for power distribution system components. An example of such an application is a vehicle, such as an aircraft. The limited space available for system components drives the requirement for high density power distribution. The power distribution system must be sufficiently compact, while still being adequately configured to distribute power to typically several loads. The loads include various types of protection against over-current, over and under-frequency, arc fault, and ground fault, to name a few potential sources of disruptions to load functionality. Circuit b...
