Abstract

PURPOSE: To suppress variation in coil current low by providing a method of limiting the maximum voltage of a coil.
CONSTITUTION: Between the driver circuit (composed of switching transistors 1 and 2 and driving voltage sources +E0 and -E0) and coil 4, diode 5 and clamp voltage source ±E, and the clamp voltage source is controlled to a voltage of ±E needed to flow a desirable current to the coil. As a result, the current amplitude of coil 4 depends only upon the clamp voltage source and is nearly under no influence of the total resistance of the resonance loop and driving voltage source. Namely, the variation in coil-4 current can be suppressed low.
