Design and testing of a solid-state power controller control and protection card for aerospace application

Advancements in the field of electrical and electronic aircraft technologies have introduced a concept of a ‘More Electric Aircraft’. This concept essentially replaces non-electrical systems on an aircraft such as Hydraulic and Pneumatic systems with electrical systems. This will create an environment with a high density of electrical loads which will require constant monitoring for electrical fault signals and rapid isolation. Advancements in power electronics and digital control systems have led to the exploration of Solid-State Power Controller(SSPC) as a replacement for the electromechanical protection devices. This thesis documents the design, development, and testing of the SSPC control card which integrates power electronics with digital control systems. The control card measurement and isolation control peripherals, design and tests’ results are thoroughly discussed. The design and test results of a protection card are explored to serve the purpose of overvoltage protection for the power semiconductor.Bachelor of Engineering (Electrical and Electronic Engineering
