Lightning is one of the most unpredictable and destructive forces in nature, and ensuring the protection and safety of aircraft in flight, as well as other modes of airborne transport, when struck by lightning presents a unique set of engineering challenges. In order to progress into a new generation of conductive carbon composites and/or embedded light-weight lightning protection systems, further...
This paper focuses on the displacement of aluminum plates subjected to the forces generated by a lightning current in order to compare modelling and experimental results directly. The electromechanical forces produced during lightning strikes can cause catastrophic damage and hence there is a need to understand the performance of existing and new materials under such extreme conditions in order to...
This paper presents the analysis of Fuzzy Logic controller for permanent magnet brushless DC motor drive for simulation and experimental results. Initially a fuzzy controller is developed by using MATLAB Fuzzy-Logic Toolbox and then inserted into the Simulink model. The dynamic characteristics of the brushless dc motor such as speed, torque, currents and voltages of the inverter components are easily...
This paper presents a 5-level multilevel inverter for low power applications that not exceeding 30 W using the common LM350 voltage regulator IC. A microcontroller with appropriate program is used to control on the biasing resistance of the IC and H-bridge inverter in order to produce the quasi-sinewave looking waveform. Analysis of the output results are shown with levels of percentage harmonics...
This paper presents the design of a high-side N-channel MOSFET driver using discrete components for 24Vdc operation. Special level shifting technique is used to increase the gate voltage higher than the supply voltage. Voltage readings at various points of the driver were also taken for reference. The designed high-side driver was tested to observe its performance with respect to different gate input...
