Electronic control circuit

A pulse discharge electronic control circuit comprising:

• an oscillator circuit for producing electrical oscillations and having a voltage divider, a first transistor and a first transformer, said voltage divider having a first resistor and a second resistor, one end of the first resistor forming a first terminal of said voltage divider, the other end of the first resistor being operably coupled to one end of the second resistor and forming therewith a second terminal of said voltage divider, the other end of the second resistor forming a third terminal of said voltage divider, said first transistor having collector, base and emitter electrodes and said transformer having primary, secondary and feedback windings, the collector electrode of said first transistor being operably coupled through the primary winding of said first transformer to the first terminal of said voltage divider, the base electrode of said first transistor being operably coupled through the feedback winding of said first transformer to the second terminal of said voltage divider, and the emitter electrode of said first transistor being operably coupled to the third terminal of said voltage divider, the first terminal and the third terminal of said voltage divider being operably connectable across a source of unidirectional electrical energy to thereby provide predetermined voltages at the first and second terminals of said voltage divider for subsequent circuit operation;
• an electrical charge storage circuit having a first electrical capacitor and a rectifying diode operably coupled in series across the secondary winding of said first transformer, the end of said first capacitor operably coupled to the secondary winding of said first transformer also being operably coupled to the third terminal of said voltage divider, thereby enabling said first capacitor to store electrical energy induced in the secondary winding as a result of the collapse of the electromagnetic field established in said first transformer by the electrical conduction of said first transistor and rectified by said rectifying diode;
• a charge control circuit having a second transistor, a first voltage threshold device, a second voltage threshold device, and a second electrical capacitor, said second transistor having collector, emitter and base electrodes, said first voltage threshold device being operably coupled at one of its ends to the second terminal of said voltage divider and at its other end to one end of said second capacitor, the other end of said second capacitor being operably coupled to the third terminal of said voltage divider, the collector electrode of said second transistor being operably coupled to the electrical junction between said second capacitor and said first voltage threshold device, the emitter electrode of said second transistor being operably coupled to the electrical junction between said rectifying diode and said first capacitor, and said base electrode of said second transistor being operably coupled to a source of biasing potential, the second voltage threshold device being operably coupled between the base electrode of said second transistor and the third terminal of said voltage divider, thereby enabling the second voltage threshold device to conduct when the charge across the first capacitor reaches a predetermined value to transfer said second transistor to a state of partial conduction, charging said second capacitor and transferring said first transistor to a state of nonconduction, delaying the next cycle of oscillation of said oscillator until the charge on said first capacitor has dissipated to the predetermined value;
• a discharge control circuit having a second transformer, a normally open, electrical trigger switch and an electrically actuatable switching device, said second transformer having a primary winding and a secondary winding, one side of the primary winding being operably coupled to the third terminal of said voltage divider and the other side of the primary winding operably coupled through said trigger switch to the electrical junction between said second capacitor and said first voltage threshold device, said electrically actuatable switching device having an input terminal, an output terminal and a trigger terminal, the input terminal of said switching device being operably coupled to the electrical junction between said rectifying diode and said first capacitor and to one side of the secondary winding of said second transformer, the trigger terminal of said switching device being operably coupled to the other side of the secondary winding of said second transformer and the output terminal of said switching device being operably connectable to a load, thereby directing an electrical energy pulse to the load whenever said trigger switch is effectively closed;
• an oscillator control circuit having a third transistor and a third capacitor, said third transistor having emitter, collector and base electrodes, the emitter electrode of said third transistor being operably coupled to the third terminal of said voltage divider, the collector electrode of said third transistor being operably coupled to the second terminal of said voltage divider, and base electrode of said third transistor being operably coupled to a source of biasing potential and additionally through said third capacitor to the electrical junction between said rectifying diode and said first capacitor, thereby transferring said third transistor to a state of conduction and hence said first transistor to a state of nonconduction, inhibiting said oscillator, during the discharge time of said first capacitor.
