It has always been the problem in the system of power supply with extracting the characteristics of electricity by high voltage side. The electromagnetic induction principle was used to design a physical power supply of electricity. The physical power supply got power parameters with current transformer from the high voltage side. The power supply using suspension electromagnetic induction as the main technical means effectively completed the adaptive regulation of operation of power supply. Experimental results show that at the line current range of 10-1000 A, the electromagnetic induction power supply can provide power of about 500 mW for the electronic devices by high voltage side. The output voltage achieves the desired effect. So the design has certain promotion value.
