Abstract
Induction power supply is a very good way of energy supply. Compared with the single battery, solar energy and laser energy supply, it has its own merits that can not be ignored. With the development of smart grid, induction power supply is widely used and the power supply of detection equipment in power grid. Current transformer and subsequent protection and processing circuit can obtain stability from busbar. Current, for the normal operation of load terminal equipment to provide a good guarantee.
Firstly, this paper introduces the research background of induction power supply mode, and illustrates the necessity of studying induction power supply mode by comparing with other different energy supply modes. Afterwards, the basic principles related to induction charging are stated, the structure and working principle of current transformer are introduced, the function, characteristics and relevant parameters of magnetic core are explained, the distribution of magnetic lines in magnetic core is simulated and analyzed, and the relationship between the power of power supply and parameters is discussed. Finally, the design of protection and processing circuit is introduced, including impulse protection circuit, rectifier circuit, filter circuit and voltage stabilization circuit.
Key words: induction charging; current transformer; simulation
