摘要：

According to the basic theory of transformer, a load model of energy harvesting coil is established. The relationships between power output, magnetization current and power output conduction angle are analyzed and verified by experiments. A novel design of current transformer energy harvesting power supply is proposed. The power output of the current transformer energy harvesting power supply is limited in a narrow range by controlling the conduction angle, so that the energy harvesting power supply can work in a dynamic range of transmission line current with low losses. The test results show that the power output of current transformer energy harvesting power supply is 2.5 W at the bus current from 40 A to 1000 A. © 2011 State Grid Electric Power Research Institute Press.
