Abstract: A localized source selection and power conversion power distribution system is described herein. In contrast to legacy systems, where multiple bus tie connectors are coupled between the centralized buses, the localized source selection and power conversion power distribution system is, in general, solely linked by a post conversion link. The localized source selection and power conversion power distribution system is also configured to effectively balance the loads of the aircraft. For example, that any power district can draw power from any power source at any time.

Abstract: A solid state switch module is provided for use in a power distribution network including an input differential protection connection for receiving a measured current value from an upstream module. The solid state switch module also includes an output differential protection connection for sending a measured current value. The solid state switch module includes a trip outlet for sending a trip signal to an upstream solid state switch, and a trip inlet for receiving a trip signal from a downstream solid state switch.

A summer adds a current input from a parallel module with the current measures by the current sensor. A comparator determines whether an amount of current lost between the solid state switch module and an upstream module is acceptable.

Abstract: A method for incorporating a set of requirements into an executable program to be run on an airborne system is provided. The method obtains the set of requirements for the program in a first format. The method uses a first tool to convert the set of requirements in the first format into a second format utilizing a markup language. The method uses a second tool to convert the set of requirements in the second format into a third format that influences a behavior of the program without changing the program. The method uses a third tool to determine whether the set of requirements in the third format incorporates all of the set of requirements in the second format in order to verify the program under a compliance standard for the airborne system without performing a verification process directly on the program.
