Research on the Control System of Car’S Power Supply

Abstract:

There are different voltages in car electrical parts, and power switches are achieved by pushing. Electromagnetic radiation which is caused by switches has a great effect on the test components and close power. The voltage caused by Electromagnetic interference could be up to 20V. Controlling panel is established by LabView and power is controlled by Matlab. The test of Car electrical parts is achieved by power. Power output is controlled by panel. Wavelet analysis is used for graphics. Collecting data is more reliable through the BP Network. The error is reduced by 30%. Amplification circuit, anti-mixing and interference circuit and triode switching circuit are designed for remote controlling power and reducing electromagnetic radiation. It raises anti-interference ability. Electromagnetic radiation is mainly focused on 0-60MHz from experiments. According to this frequency brand, we adopted measures for reducing electromagnetic radiation by 8.6dB.
