Abstract

The invention relates to a low-current high-accuracy variable voltage output device which comprises a linear voltage stabilizing source. The output end of the linear voltage stabilizing source is connected with the input end of a pulse width modulation circuit. The output end of the pulse width modulation is connected with the input end of a sixfold-voltage boosted circuit. The output end of the sixfold-voltage boosted circuit is connected with the input end of an adjusting indicating circuit. The sixfold-voltage boosted circuit outputs high-voltage electricity to electric equipment. The output end of the adjusting indicating circuit is connected with the input end of the linear voltage stabilizing source. The linear voltage stabilizing source, the pulse width modulation circuit, the sixfold-voltage boosted circuit and the adjusting indicating circuit form a closed loop feedback control circuit. The pulse width modulation circuit generates square signals which are subjected to transformer T1 coupling, secondary boosting is carried out, high voltage output by the sixfold-voltage boosted circuit is subjected to voltage dividing, on one hand, feedback voltage is output to an upper computer in proportion, the upper computer is used for monitoring output voltage and current, on the other hand, the feedback voltage is under closed loop control, changing of the output voltage is tracked, and by fine tuning of voltage input into MOS tubes Q1 and Q2, stability of the output voltage is achieved.

Description

technical field [0001] The invention relates to the field of industrial detection, in particular to a low-current high-precision variable high-voltage output device. Background technique [0002] In the industrial detection methods, the sensors that accept the energy change of rays mainly adopt photomultiplier tubes, ionization chambers, etc. The use of these two types of sensors requires an externally stable bias voltage of several thousand volts, and the voltage requirements can be set arbitrarily. Voltage value, or the required voltage can be set remotely by means of analog quantity.
