Stable and Efficient High-Tension Communication Power Supply Based on Electromagnetic Coupling

High-tension power delivery based on electromagnetic coupling for hot spot temperature in power equipment and the systems of current on-line monitoring of early warning is an effective way to solve the 'energy island' .In this paper, a miniature, low cost, high reliability, easy installation and maintenance communication power supply that based on electromagnetic coupling has been designed, it also can provide a lasting and stable power output. Since the central position of the receiver coil and the rectifier filter circuit in the power supply，Optimization design and simulation have been made for the coil and the rectifier filter circuit. A three-dimensional coil was used as the receiving coil, optimization results show that load power is 10.18w at the conditions of low-frequency and high-voltage. It achieves the objective of the miniature and low-cost. The simulation results of rectifier and regulator show that the system can transfer energy at the range of approximately 2% fluctuation.
