Abstract
Abstract D R A W I N G A POWER SUPPLY IS CONNECTED ACROSS A CAPACITOR, VIA A RESISTOR AND THE PRIMARY WINDINGS OF A PULSE TRANSFORMER, FOR CHARGING THE CAPACITOR TO A PREDETERMINED VOLTAGE. A PULSE GENERATOR EXCITES A TRANSISTOR SWITCH CONNECTED ACROSS THE PRIMARY WINDINGS OF THE TRANSFORMER AND THE CAPACITOR TO PERIODICALLY DISCHARGE THE CAPACITOR THROUGH THE PRIMARY WINDINGS. THE PERIODIC DISCHARGES OF THE CAPACITOR THROUGH THE PRIMARY WINDINGS OF THE PULSE TRANSFORMER INDUCES IN THE SECONDARY WINDINGS OUTPUT PULSES WHICH HAVE AN AMPLITUDE PROPORTIONAL TO THE CAPACITANCE OF THE CAPACITOR.
