ABSTRACT:
The distributed capacitance between coil turns in a coil device is increased, and a coil inductance and a low-pass filter are formed, whereby overvoltages and high frequency voltages are suppressed. The increased distributed capacitance is attained by inserting a ferroelectric insulator, such as a ceramic material, between the coil turns or by winding a metal foil-containing insulator film in the shape of a tape, round a coil conductor.
