PCT No. PCT/HU85/00053 Sec. 371 Date Jan. 29, 1987 Sec. 102(e) Date Jan. 29, 1987 PCT Filed Sep. 6, 1985 PCT Pub. No. WO86/06226 PCT Pub. Date Oct. 23, 1986.A circuit arrangement for generating high voltage pulses from DC voltage. The circuit includes a transformer comprising at least two primary windings and secondary windings, in which the primary windings are serial connected with at least one diode, a switching circuit 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 connected resistors are inserted between the input of the transistor amplifier and the output of the control circuit. The emitter-collector-section of a first transistor is connected to the common terminal of both the resistors. A voltage divider is connected to the base of the first transistor. The leg of the voltage divider on the collector side of the first transistor includes two serial connected resistors. A second capacitor is connected between (a) the point between the two serial connected resistors in the leg of the voltage divider on the collector side of the first transistor, and the common terminal of the primary winding of the transformer and of the switching transistor. A current sensing resistor is connected in series with the emitter-collector-circuit of the switching transistor.
