Abstract An application scheme of Poe based Ethernet technology in meteorological intelligent sensor system is designed. The working principle and implementation method of Ethernet power supply system (POE) based on IEEE802.3af Ethernet power supply industry standard are experimentally analyzed. The power supply part of the meteorological intelligent sensor makes full use of Poe technology to provide current on the network cable transmitting data, which greatly reduces the complexity of the power supply system and improves the reliability of the system power supply design. Through the test of the actual system, the function and performance of the meteorological intelligent transmission system have achieved the expected results.

This paper introduces the working principle of power system on tracked vehicles. Tracked vehicles with high pressure air or pulling the battery starts, due to the main power supply system power supply, can't fight. Through an analysis on the failure of electricity generation of the main power system, a tachometer sensor is designed and used as main power providing excitation and causing an electric potential difference, which realizes passive power supply after non-battery starting.

Simulation Results

The objective of this work is to simulate a kind of passive harmonic filter based on IGBT to improve the power factor of the power supply system, then to verify the feasibility of reactive power compensation and harmonic suppression. According to the topological structure and working principle of passive dynamic harmonic filter based on IGBT, the simulation model of the system has been set by the Simulink tool. Simulation results show that the passive dynamic harmonic filter based on IGBT can compensate the corresponding reactive power and suppress harmonic in the power grid. The research of this paper has laid a theoretical foundation for this filter in industrial applications.

And Performance

This paper represents the study of different types of single phase AC to DC step down converter. Performances and outputs have analyzed depending on the equations. Different parameters such as voltage gain, harmonic contents in input current, and parameters of changing output voltage are compared different type of single phase AC to DC converters. AC to DC converter is defined as rectifier. The main power supply system is alternating in nature. Rectification action is required to obtain DC supply from the main power supply which issinusoidal.
