Abstract
An inverter switches input voltage Vin to flow an excitation current to excitation winding Np of a transformer and output to a discharger an alternating voltage Vout from the output winding Ns. In an output circuit flowing a current to the discharger, a voltage-responsive connector is connected in series with the winding Ns to interrupt or connect the output circuit according to a voltage applied to between opposed electrodes. The voltage-responsive connector has characteristics of keeping the electrodes in an insulated state until an instantaneous value of the alternating voltage reaches a predetermined value, and holding the electrodes in a conduction state while the instantaneous value of the alternating voltage has reached the predetermined value and continues to exceed the predetermined value, and quickly returning the electrodes to the insulated state when the instantaneous value of the alternating voltage has fallen below the predetermined value.
