Abstract From the Canadian patent

A circuit arrangement for generating high voltage pulses from the circuit includes a transformer comprising at least two primary windings and secondary windings in which the primary, windings are connected with at least one diode a switching cir-, cuit and a voltage source. A first capacitor is connected in parallel with the first primary winding and diode and in series, with the secondary primary winding. The switching circuit is formed from the emitter-collector-section of a switching transistor. The output of a transistor amplifier is connected to the base of the switching transistor. The input of the transistor amplifier is coupled with the output of a control circuit. Two serial …
