A kind of ultraviolet lamp power supply

Abstract

The invention relates to the technical field of a power supply, and specifically to an ultraviolet lamp power supply. The ultraviolet lamp power supply is simple in circuit structure, and capable of flexibly adjusting pulse output frequencies and charging voltages in single times, and the power of the power supply is easy to increase. The ultraviolet lamp power supply comprises a main circuit, a starting circuit, a control circuit and a detection circuit, wherein the main circuit comprises a main voltage input voltage and a capacitance charge-discharge unit; the starting circuit comprises a starting voltage input unit, a starting unit, a PWM controller and a pulse xenon lamp; the detection circuit comprises a current detection unit and a voltage detection unit; the control unit comprises an MCU unit; the main circuit, the starting circuit and the detection circuit are all connected with the MCU unit; the main voltage input unit charges a main capacitor to supply a discharge voltage; the starting voltage input unit supplies the starting voltage to the starting circuit so as to control the starting of the pulse xenon lamp, and supplies pre-ignition current through the PWM controller so as to realize a pre-ionization state of the pulse xenon lamp; the voltage detection unit detects the voltage of the main capacitor; and the current detection unit detects the current of the pulse xenon lamp.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply for ultraviolet lamps. Background technique [0002] Ultraviolet is Ultraviolet in English, referred to as UV. Ultraviolet lamps are lamps made of special effects of ultraviolet rays. They are widely used in sewage treatment, sterilization, printing and curing, bonding and other fields. The strong ultraviolet lamp tube is made of high-quality pure quartz tube material, and the ultraviolet transmittance of pure quartz material per mm thickness is about 87%, which is much higher than other materials. The principle of ultraviolet sterilization is to cause some photosensitive molecules to induce free radicals and cause lipid peroxidation through radiation to damage the organism. When it acts on microorganisms, the nucleic acid that constitutes the basic component of the living body will mutate when it reaches a certain dose of ultraviolet radiation. Causes prot...
