EMI-EMC Analysis

Now a days the vehicle electronics in the auto-motive industry is facing new challenges, the safety of braking system has become a critical function. The number of electrical and electronics devices, accessories and loads, like starter motor, alternator, wiper motor, relays, night heater, light control module, speedometer, accelerator potentiometer, cruise control, compressor, brake Anti-brake system control unit, air dryer, engine brake valve, brake calipers, valves, valve blocks, diaphragm units, actuators are increasing day to day. The research work is carried out to investigate the conducted and radiated Electromagnetic-Interference due to various sources like, conductor and ground, two conductors and ground of different layouts. Parameters are estimated using analytical calculations and simulated using Simulation software. The estimated parameter values of electric field intensity, magnetic field intensity, frequencies and impedance are validated. Antenna factor of micro strip antenna are validated with dipole antenna and rectangular wave guide. These proposed solutions will primarily focus on causes of Electromagnetic interference and later eradication of EMI.
