[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0024] As Figure 1 shown, in one embodiment, a high-voltage pulse generator with adjustable voltage includes a protection and voltage stabilization module 1 and a boost module 2, and the protection and voltage stabilization module 1 and the boost module 2 are electrically connected.

[0025] Among them, the protection and voltage stabilization module 1 includes an anti-reverse protection module 11 and a low-dropout linear voltage regulator module 12. The protection and voltage stabilization module 1 is used to protect the boost module 2. The boost module 2 includes a DC / DC first-stage boost module 21 and a DC / DC second-stage boost module 22. The boost module 2 is used to adjust the output voltage.

[0026] As Figure 1 shown, in this embodiment, one end of the anti-reverse protection module 11 is electrically connected to the low-voltage input terminal 3, and the other end of the anti-reverse protection module 11 is electrically connected to the low-dropout linear voltage regulator module 12. The anti-reverse protection module 11 can detect the polarity of the power input. If the polarity is found to be reversed, the circuit will be automatically disconnected to prevent the reverse flow of current from damaging the components in the circuit. A suitable type can be selected according to specific application requirements and design considerations.

[0027] Exemplarily, the anti-reverse protection module 11 can adopt:

[0028] (1) Diode: A diode is connected in parallel in the circuit, and the circuit will work only when it conducts in the forward direction;

[0029] (2) MOSFET reverse voltage protection: A circuit composed of an N-channel MOSFET and a resistor is used. By controlling the conduction state of the MOSFET, the reverse voltage is prevented from passing through. When the input voltage has the correct polarity, the MOSFET conducts and the circuit works normally; when the input voltage is reversed, the MOSFET is cut off and the resistor limits the reverse voltage;

[0030] (3) Negative temperature coefficient thermistor: It shows a low resistance under normal working voltage, but when there is a reverse voltage in the circuit, its resistance value will increase rapidly, thereby limiting the reverse current and playing a protective role.

[0031] As Figure 1 shown, in this embodiment, the other end of the low-dropout linear voltage regulator module 12 is electrically connected to the first-stage boost module 21. The low-dropout linear voltage regulator module is used to protect the boost module 2 and stably outputs the input unstable DC voltage through the internal feedback control circuit.

[0032] As Figure 1As shown, in this embodiment, one end of the first-stage boost module 21 is electrically connected to the other end of the second-stage boost module 22. The first-stage boost module 21 is used to adjust the boost range, so as to adapt to different types of pulsed xenon light sterilization lamps; while the second-stage boost module 22 is used to proportionally increase the output voltage of the high-voltage output terminal 4. The other end of the second-stage boost module 22 is electrically connected to the high-voltage output terminal 4, and the excitation voltage is output through the high-voltage output terminal 4.

[0033] Exemplarily, after the first-stage boost module 21 raises the input low voltage to 0.3 kV - 1 kV, the second-stage boost module 22 then raises the voltage value after the first-stage boost to 4.5 kV - 15 kV at a fixed ratio. The adjustable voltage range can adapt to the trigger voltages of various pulsed xenon light sterilization lamps.

[0034] As Figure 1 shown, in this embodiment, the first-stage boost module 21 is electrically connected to the data communication terminal 5. The data communication terminal 5 is used to set the target voltage and conduction time, so as to excite pulsed xenon light sterilization lamps of different specifications.

[0035] Furthermore, a voltage-dividing resistor 211 is provided at one end inside the first-stage boost module 21. The target voltage can be set through the voltage-dividing resistor 211 or a target value can be given through the data communication terminal 5; and a voltage collector 212 is provided at the other end inside the first-stage boost module 21, which can collect the voltage value after the first-stage boost in real time.

[0036] In addition, the data communication terminal 5 is selectively connected to a control display. It can not only be used to set the parameters of the module, such as setting the target voltage and other operating parameters, but also can display the current output voltage value in real time, which can conveniently monitor the operation of the first-stage boost module 21, ensure the stable operation of the circuit and meet the expected output requirements.

[0037] Working principle: According to the excitation voltage values of pulsed xenon light sterilization lamps of different specifications, the target voltage value and the high-voltage conduction time are set through the voltage-dividing resistor 211 or an externally given voltage signal, and then the boost module 2 is protected by the protection and voltage stabilization module 1, so that the high-voltage value at the output end can be flexibly adjusted to adapt to pulsed xenon light sterilization lamps with different excitation voltages, effectively improving the service life and utilization rate of the pulsed xenon light sterilization lamps, and reducing the replacement frequency and production cost.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
