Abstract

PURPOSE:To raise the efficiency of a high-voltage power supply device, dispense with an auxiliary high-potential power supply circuit and reduce the weight of the device, by inserting a series control transistor of a series regulator into a low-potential output line for the output of a converter of fixed pulse width. CONSTITUTION:The series control transistor 40 of the series regulator 46 is inserted into the grounded potential line of the converter 33 of fixed pulse width. The input voltage to the series control transistor 40 is regulated by a chopper regulator 49 so that the voltage is kept at alow constant level independently of the output voltage of the transistor. Therefore, the efficiency of the device is raised much more than a conventional device wherein the fluctuating part of the output voltage is all applied to a load. No auxiliary high-potential power supply circuit is needed.
