Abstract

PURPOSE: To make it possible to use analog IC by performing sine wave coil current drive only by a unipole electric power source by coupling switches and diodes with the driving coil and resonance capacitor of a bubble chip.
CONSTITUTION: With only switch S3m closed after the capacitor voltage reaches +V0, coil current flows by way of diode D2m, capacitor C, driving coil L, and S3m opened and S2p closed at 1/4 period later, the coil current flows by way of S2p, C, L, and D3p. With S1m instantaneously closed at 1/4 period later, v1 is set to 0V and the capacitor voltage is held at -V0. Next, with S2p opened and S3p closed, the coil current flows through L, C and D2p. With S3p opened and S2m closed at 1/4 period later, the coil current flows through D3m, L, C, and S2m. As a result, coil current ic of a sine wave can continuously be flowed.
