STABILIZED HIGH-VOLTAGE SOURCE Russian patent published in 2003 - IPC

FIELD: radio engineering. SUBSTANCE: stabilized high-voltage source can be utilized for supply of tubes of X- ray apparatuses, TV picture tubes, printers, photoelectron multipliers and other highvoltage equipment. In compliance with invention Kerr cell is employed as measurement converter, its input being connected to leads for connection of load and its output being connected through photoconverter and amplifier to input of comparator of continuous stabilizer. Stabilized source functions as follows: with rise of output voltage light intensity across output of cell grows in correspondence with graduation graph. After conversion of optical signal to electric one by photoconverter and its amplification, signal is fed to input of comparison element with voltage level exceeding value of reference voltage. Comparator forms output signal of such sign under which regulation element of stabilizer closes diminishing voltage across output of multiplier. Process goes on till moment when voltage across output achieves preset stabilization voltage. With fall of output voltage feedback network generates such voltage to comparison element under which comparator generates signal opening regulation element. As result output voltage rises to previous value, that is, is stabilized. EFFECT: increased operational reliability of stabilized high-voltage source due to exclusion of any resistance coupling through divider of high-voltage output of source and low- voltage input of regulation system. 3 dwg
