<p>High voltage generator comprising several voltage multiplying stages connected in series, each comprising a diode and a capacitor one terminal of which being connected to the cathode of the respective diode, every cathode of a diode being connected to the anode of the diode of the next voltage multiplying stage, a clock generator generating two clock pulses being 180° out of phase to one another and being supplied alternately to the other terminal of the capacitors of successive voltage multiplying stages, the last diode in the series supplying a high voltage output and said high voltage output being connected to feed-back means, modifying said two clock pulses in dependence on the voltage level on the high voltage output, at least the capacitor (Cn) in the last voltage multiplying stage receiving a control current (I1) determined by said feed-back means instead of one of both clock pulses.</p> |
