Abstract
PURPOSE: To obtain a device suitable for integrating with other circuits and permitting speedy charging by feeding back the secondary side current to an auxiliary amplifier switching element and thereby controlling an oscillation transistor.
CONSTITUTION: When switch 1 is closed, current flows from low voltage power supply 2 to elements 4, 5, 10, 7. As a result, auxiliary amplifier switching element 6 becomes conducting. By this, oscillation amplifier element 3 becomes conducting. When element 3 becomes conducting, the primary winding 10a of oscillation transformer 10 is made conducting, and charging current is supplied to condenser 12 from the secondary winding 10b. When oscillation transformer 10 is saturated, a voltage of polarity opposite to that shown in the drawing is induced in auxiliary winding 10c. As a result, element 6 becomes non-conducting, and also element 3 becomes non-conducting. When the opposite polarity voltage induction period in auxiliary winding 10c has passed, element 6 becomes conducting and the above- described charging process is repeated.
