PURPOSE:To remove the ripple components caused by a commercial low frequency power source by applying a negative bias to the second inductor. CONSTITUTION:When a low frequency power source 1 is thrown, an oscillation capacitor 7 is charged through the first inductor 6 and a negative bias coil 81. When the charged voltage of the capacitor becomes higher than the predetermined value, an oscillation occurs via the coil 81, the second inductor 8, a thyristor 9, and an oscillation capacitor 7, and the bias of the coil 81 is suitably regulated. Thus, the oscillation output voltage b from which ripple components caused by the low frequency power source are removed with constant peak value can be obtained from the first inductor 6. |
