PURPOSE:To synchronize the oscillating operation of an oscillator circuit by detecting oscillation start of a closed oscillator circuit and forcibly oscillating the remaining closed oscillator circuits. CONSTITUTION:Oscillation capaictors 3a, 3b are charged through a phase advance capacitor 9 and a current limiting choke 2 by making an AC power source 1 ON. When a charging voltage becomes higher than the predetermined value, thyristors, 5a, 5b are conducted, and an oscillating current will flow in a circuit of the capacitors 3a, 3b, thyristors 5a, 5b, step-up inductors 4a, 4b, secondary coils 41b, 41a of step-up inductors 4a, 4b and the capacitors 3a, 3b. At this time the inductors 4b, 4a can be approximately simultaneously saturated by the current flowing through the secondary coils 41b, 41a, thereby coinciding in the period of the oscillations of the oscillator circuits 61a, 61b. Accordingly, a high oscillation voltage (c) synthesized with the oscillating voltages (a), (b) of both the oscillator circuits can be obtained at both ends of the oscillator circuits 61a, 61b. |
