Abstract

PURPOSE: To prevent an overvoltage applied to a switch to make it possible to use a low-dielectric strength transistor for switch, by clamping the point in the switch side of the coil of a parallel resonance driving circuit by the power source voltage.
CONSTITUTION: Middle point 22 between switching transistor 20 of the coil for rotating magnetic field generation and diode 21 is connected to negative power source -V by clamp diode 23. Thereafore, voltage VX does not become a vibrating waveform when forward current IX flowed to the coil is stopped. Consequently, a required dielectric strength of transistor 20 is the power source voltage approximately. By connecting clamp diode 30 between positive power source +V and middle point 33 between transistor 31 and diode 32, the vibrating waveform at point 24 can be prevented when negative current IY flowing to the coil is stopped, and a dielectric strength of transistor 31 can be the power source voltage approximately.
