Abstract
- The objective of this paper is to evaluate the engineering feasibility of high-frequency magnet systems for the magnetic hyperthermia cancer therapy. For the effective induction heating properties of the magnetic particles with a short-time cancer therapy, the target specifications of the magnet system are 0.06 T of the peak magnetic field with 200 kHz of the operating frequency and with 300 s (5 minutes) of the continuous or intermittent operation time. From the results, the magnet designed using 200-A copper Litz wires and a magnetic core enables the reduction of one turn voltage of the coil windings to 8.47 kV. The winding loss is 3.89 kW, which suggests that the magnet can be operated without a water cooling system. Single voltage source high-frequency inverter using commercially available SiC-MOSFET (<1.2 kV) can drive the magnet with balancer circuits using variable series capacitors. [ABSTRACT FROM AUTHOR]
