Claims

[Scope of utility model registration request]

In an inverter that passes current to the primary winding of a transformer through a pair of transistors that are alternately switched and driven with different phase relationships, the control voltage of one transistor is an integral that integrates the induced voltage in the primary winding. a comparator for comparing the output of the integrator with a level voltage, a flip-flop set by the control voltage and reset by the output of the comparator, and logic for receiving the output of the flip-flop and the control voltage. A transistor inverter, characterized in that it is applied to one of the above transistors via a product element.
