Abstract
A charging circuit charges a first capacitor to a first voltage and a second capacitor, via a potential divider to a second voltage smaller than the first voltage. A trigger circuit repeatedly triggers a thyristor which discharges the second capacitor into the primary winding of a pulse transformer whose secondary winding is connected across a diode in series with the first capacitor between output terminals.
