Abstract

The invention discloses a voltage stabilizing control circuit applicable to a flow cytometer. The circuit comprises a high voltage module, a control module and an adjusting module, wherein the high voltage module is used for providing direct current voltage of a preset value; the control module is used for outputting the adjusting voltage; the adjusting module is connected with the high voltage module and the control module and used for performing linear adjustment on the direct current voltage output by the high voltage module according to the adjusting voltage output by the control module to obtain the direct current voltage of the needed value to be supplied to a snow slide light emitting diode. By performing linear adjustment on the direct current voltage input by the high voltage module through a linear adjusting unit in the adjusting module, linear control over the APD power voltage is achieved, and the stable direct voltage is provided for APD.

Description

technical field [0001] The invention relates to a control circuit, in particular to a voltage stabilization control circuit suitable for a flow cytometer, and belongs to the technical field of circuit control. Background technique [0002] In the biological and medical fields, flow cytometers are often used to quantitatively count and analyze the types and quantities of biological cells. In this process: first, the samples are stained with fluorescent reagents; The laser beam irradiates it. Since different types of dyed sample particles will emit fluorescence signals of different wavelengths and different energies under the excitation of the laser beam, multiple photoelectric receivers are used to receive different fluorescence signals. These fluorescence signals After irradiating on a photoelectric sensor such as an avalanche diode, an electrical pulse signal that can reflect the characteristics of the sample particles is generated. The electrical pulse signal undergoes si...
