ABSTRACT:
A d.c. high voltage power source comprising: a d.c. high voltage generator; a voltage divider for detecting an output voltage of said generator, which is connected between the high voltage output terminal of said generator and ground potential; an error amplifier, one input terminal of said error amplifier being connected to the voltage dividing point of said voltage divider; a reference voltage source connected between the other input terminal of said error amplifier and ground potential; control means for stabilizing said output voltage of said generator by the output of said error amplifier so as to maintain said output of said error amplifier substantially equal to zero; an ammeter connected between the low voltage output terminal of said generator and ground potential; a resistor connected between the non-grounded terminal of said reference voltage source and said low voltage output terminal of said generator, the resistance value of said resistor being equal to that of the resistance to ground of said voltage dividing point of said voltage divider.
