Non-contact energy transfer systems are used in various fields in industry. A high-frequency constant current must be supplied to the transmission line of this system. Pick-up coils that are magnetically coupled with the transmission line are used to receive the power from the transmission line. The received power is converted into a constant voltage and used as a power source.When there are two or more pick-up coils on the transmission line, the output of one pick-up coil does not affect the other pick-up coils on the transmission line if the transmission line current is constant. We have proposed that an immittance converter be used to realize a constant current source and a constant voltage source. The input impedance of the immittance converter is proportional to the admittance of the load connected across output terminals of that. In this converter, the output current is proportional to the input voltage, and the output voltage is proportional to the input current. Consequently, it transforms a constant voltage source into a constant current source and a constant current source into a constant voltage source.In this paper, a cascade configuration of a T-LCL-type immittance converter and a T-CLC-type immittance converter in a non-contact energy transfer system is proposed.
