Abstract

A single-ended MOSFET DC-to-RF inverter connected to the load consisting of a capacitor and a planar coil, which are connected in serial, is described to remove water drops from the surface of a small mirror. The planar coil is made of a patterned printed circuit board resembling a swirl. Induction heating is accomplished on a sheet of iron by an RF current flowing through the planar coil. When the surface temperature of the mirror attached to the iron sheet was 40°C, the power of the MOSFET DC-to-RF inverter operating at a resonating frequency of 52.3 kHz was supplied from a DC power supply at an output power of 22 W. This temperature is high enough to remove water drops from the surface of the mirror, even if the output power is small
