Abstract
A high voltage generator using a flyback transformer to generate high voltage pulses and including a control switching transistor inserted in a power supply circuit in a manner to be turned off during a trace interval. The amount of electric energy accumulated in a resonance circuit is intermittently controlled by the on-off action of such switching transistor, so that the level of the high pulse voltage outputted via the transformer can be maintained constant to consequently enhance the response characteristic in the voltage regulation while minimizing the number of required component elements.
