Abstract
Appling magnetic nanoparticle (MNP) in curing cancers has been a significant subject of medical research. A variety of switched-mode resonant inverters using voltage-fed-type high-frequency applicator with power MOSFET (metal oxide semiconductor field effect transistor) gate has been recently developed for medical use in electromagnetic thermotherapy. In this paper, a MNP heating system is presented and the electrical circuit characteristics of resonant components are analyzed. A half-bridge induction heating incorporate component functions directly at the applicator thereby reducing the size, weight, and cost of MNP heating systems. Preliminary heating results show a rise of about 3.8°C with 10-nm MNP for a 220-kHz frequency during the first 20 min.
