Abstract

PURPOSE:To obtain a X-ray radiation preventive protection circuit with a high precision and a simple circuit constitution by adding the negative voltage which is obtained by rectifying the flyback pulse voltage, and the voltage which is proportional to the anode current of CRT generated at the low potential-side terminal of the high-voltage winding.
