CAN communication of power converters system for aerospace application

This final year project is one of the requirements to get a bachelor of engineering degree in Nanyang Technological University. The project is Industrial Sponsored Project (ISP) with Rolls-Royce Singapore Pte Ltd. The project aims to design the CAN communication system for the aerospace power system from the scratch. Hence, some studies were done to understand the CAN communication protocols and some experiments were carried out to verify the performance of the CAN devices. Power electronic converters will be widely used in future more electric aircrafts (MEA). The next generation of MEA is not only focusing on power electronic converters and high frequency generator supply but also explore the communication system. To achieve high security and safety requirement for the future MEA, several electrical parameters are measured and controlled through the CAN prototype to ensure the system is stable. Hence, the CAN communication between several power electronic converters (SEMIKRON SKAI2-HV module) and TMS320F28335 DSP was carried out to identify the parameter of the MEA application. Experimental setup was carried out to verify the communication system of aerospace applications. The asynchronous interrupt was realized using a Spectral Digital eZdsp and LCD module. Two types of interrupts were also discussed according to the experimental results. Furthermore, the codes for parameter display were created in Matlab State Flow blocks and Simulink models. This parameter display could be useful for further applications in the real system. The final product of the project was a Matlab Graphic User Interface (GUI) which was designed to control the SEMIKRON SKAI2-HV module.Some algorithms are created to make a real-time plotting for some signals from the inverter module by employing a CAN Analyzer.Bachelor of Engineerin
