Abstract
Disclosed herein is an assembly for controlling solid-state switching elements in an aircraft having at least one power pathway comprising at least one power line supplying power to at least one item of equipment on board an aircraft from at least one electrical power source via a power switch, and at least one control member controlling at least one power switch according to control signals arising from a control means. The control assembly comprises a single power supply supplying power to the control members.

An assembly for controlling solid-state switching elements in an aircraft having at least one power pathway comprising at least one power line supplying power to at least one item of equipment on board an aircraft from at least one electrical power source via a power switch,
- at least one control member controlling at least one power switch according to control signals arising from a control means,
- wherein the control assembly comprises a single power supply supplying power to all of the control members, the single power supply being electrically isolated with respect to the control means,
- wherein the assembly comprises at least one analogue level offset means positioned between the control means and a control member, and
- the analogue level offset means being capable of maintaining the amplitude of the control signal transmitted by the control means while changing the reference potential of the control signal from the reference potential of the control means to the reference potential of the control member and of the isolated power supply.
