A three phase inverter, controlled by SPWM technique driving a three phase induction motor with low pass passive filter is implemented on MATLAB simulink platform. The harmonic content present in the three phase inverter is analyzed using FFT tool. Hardware implementation of the same is done using DSP (TMS320F2812) controller. The output from the inverter is connected to a three phase induction motor...
This paper presents miniature hardware model of 6 pulse controlled rectifier circuit for a monopolar HVDC link. The Controlled rectifier is interfaced with PIC (16F72) microcontroller for generating various firing angles. The results of output voltage are recorded using digital oscilloscope and are compared with the theoretical values at different firing angles. Performance analysis parameters such...
In advanced search engines queries are being expressed in natural language as it seems to be the next step for developing future systems. Hence, users can express what they are searching for in a sentence form. The Semantic Web framework is our chosen field. This approach is to build a complete and meaningful Web Search using a Natural Language system. The process is complete when it covers pre-processing,...
Materials used in the manufacture of polymeric insulators were ethylene propylene diene monomer (EPDM) and silicone rubber (SR). Non ceramic insulators have shown good performance even in hostile environments. Silicone rubbers helped considerably to eliminate the contamination problem. Silicone rubbers have low surface energy which offers a hydrophobic surface, which does not wet the surface, offering...
Contamination flashover is a major concern affecting the reliability of power systems. Industries switched over from porcelain to polymers due to lighter weight and superior contamination performance. Polymers especially silicone rubbers (SR) helped considerably to eliminate the contamination problem. Bio contamination is a growth of fungi or other micro organism which colonize on the surface of the...
