Abstract

In systems in which inductive coupling between a pancake-shaped coil on the surface of the body and a similar coil within the body is utilized for the transfort of electromagnetic energy, the minimization of temperature rise in the tissue is intimately related to the achievement of minimum losses in the region of the implanted coil. The new class of amplifiers, named "class E", for inverter is defined and is illustrated by a detailed description and a set of desist equations for one simple member of the class. For TET circuit the authors measured 65 to 76 percent efficiency at 1985kHz at 30 to 50 W output from IRF250 MOSFET transistor.
