Claims

[Scope of utility model registration request]

The base drive current of the pair of transistors is forced to be alternately interrupted by the output of the control circuit, and the collector current of the pair of transistors excites the center-tapped primary winding of the output transformer, producing a square wave output on the secondary side. In the control inverter to be obtained, a multi-stage smoothing circuit using an L-shaped circuit of a reactor and a capacitor in the final stage is provided at the inverter input terminal, and a self-ignition circuit is connected in series with the smoothing capacitor in the final stage of this smoothing circuit. Insert a Cyrisk with
A control inverter characterized in that a voltage across a smoothing capacitor is used as a drive power source for a pair of transistors, a control circuit, and a power source.
