Embodiment Construction

[0044] figure 2 A circuit board is shown, in particular a switching circuit board, comprising a single galvanically isolated power supply with respect to the ground of the control device 3 and control signals transmitted via analog level shifting devices 15a, 15b. and figure 1 Similar elements have the same reference numerals.

[0045] The control mechanisms 9a, 9b integrated into the respective switching circuit boards can be made of non-galvanically isolated discrete components.

[0046] The architecture comprises a single galvanically isolated power supply 3, which supplies power to each power supply path 1a, 1b. Using a single power supply can solve, or at least substantially reduce, the problems associated with electromagnetic compatibility constraints.

[0047] The isolated power supply 3 and the supply paths 1a, 1b have the same reference potential. The voltage magnitude of a single supply depends on the type of power switch selected.

[0048] The control mechanis...

Abstract

The present disclosure relates to an assembly for controlling solid-state switching elements in an aircraft, the assembly having: at least one power supply path (1a, 1b) comprising: at least one power supply line (6a, 6b) for receiving power from at least one The power supply supplies power to at least one equipment item onboard the aircraft through a power switch (7a, 7b); and at least one control mechanism (9a, 9b), which controls at least one device according to a control signal generated by the control device (10a, 10b) A power switch (7a, 7b), the control assembly includes a single power source (3) that supplies power to the control mechanism (9a, 9b).

Description

technical field [0001] The technical field of this disclosure is that of solid state power controllers, and in particular the control of such controllers. Background technique [0002] A solid-state power controller (SSPC) is a component capable of managing the distribution of power to the aircraft load via the lines transmitting electrical power and the protection of these lines. The solid-state power controller consists of a control section and a power section, and the solid-state power controller includes switching components based on semiconductor elements. The term "aircraft load" is understood to mean an on-board item of equipment that consumes electrical power. They are usually mounted on a circuit board. [0003] These circuit boards, commonly referred to as power distribution boards or SSPC boards, include at least one power supply path controlled by a solid state power controller or SSPC controller. A circuit board usually consists of multiple power supply paths...
