Abstract
Abstract A PULSE PRODUCING CIRCUIT INCLUDES A PAIR OF SUPPLY LINES TO WHICH POWER IS SUPPLIED BY AN OSCILLATOR. WHEN THE OSCILLATOR SUPPLIES POWER TO THE LINES, IT CHARGES TWO CAPACITORS AT THE SAME TIME. THE FIRST CAPACITOR IS CONNECTED ACROSS THE LINES IN SERIES WITH A RESISTOR, AND WHEN THE CHARGE ON THIS CAPACITOR REACHES A PREDETERMINED VALUE A BREAKDOWN DEVICE CONDUCTS, AND THE FIRST CAPACITOR DISCHARGES TO TURN ON A SWITCH. THIS SWITCH THEN PROVIDES A DISCHARGE PATH FOR THE SECOND CAPACITOR WHICH DISCHARGES THROUGH A LOAD.
