Problems solved by technology

When the power supply voltage is normal, this type of device does not work. When the power supply voltage surges, this type of device quickly conducts to absorb the energy of the overvoltage surge to protect the electrical equipment. The power consumption is relatively large, so devices with low power are easily damaged, and high-power devices are generally expensive and bulky, so the application will be subject to certain restrictions
The accuracy of this type of device is not high, there is a certain deviation, it is not suitable for use in some electronic equipment with high requirements
At the same time, such devices must be integrated on the necessary circuit boards and require further design processing

Abstract

The invention discloses a DC transient surge voltage suppression module, which comprises a voltage acquisition and comparison circuit, a power execution device and a driving circuit, and is characterized in that the voltage acquisition and comparison circuit is used for acquiring a current loop voltage, comparing the current loop voltage with a preset voltage threshold value and outputting a control signal according to a comparison result, the power execution device is used for outputting current to a load, and the driving circuit drives the power execution device according to the control signal output by the voltage acquisition and comparison circuit, so that the power execution device is in a complete conduction state or a variable resistance area state. According to the invention, the suppression module detects the current loop voltage through the voltage acquisition and comparison circuit, compares the current loop voltage with a preset voltage threshold value, and then outputs a control signal to control the working state of the power execution device through the driving circuit, so that the output voltage value is within the specified input range of the post-stage electric equipment.

Description

technical field [0001] The invention relates to a DC transient surge voltage suppression module. Background technique [0002] For some electronic equipment in specific environments and purposes, there are often high-voltage power surges from a few microseconds to hundreds of milliseconds in the power supply. The electronic products in these equipment must not only withstand transient voltage surges without being damaged, And in many cases must also operate reliably throughout voltage surges. In order to protect these electrical equipment and prevent them from being damaged by surge voltage, it is necessary to perform anti-surge treatment on the power supply circuit of the electronic equipment. [0003] A common surge suppression method is to connect voltage clamping devices such as transient voltage suppression diodes, solid-state discharge tubes, and varistors in parallel at the input end of the power supply. When the power supply voltage is normal, this type of device d...
