Description

Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to an AI-controlled computer power supply adaptive global voltage switching device. Background Technology

[0002] In the field of computer power supply applications, the mains voltage used in different countries and regions around the world varies, requiring existing computer power supplies to be adapted to different voltage environments. Currently, one mainstream adaptation method is to set a manual switch on the power supply. Users must manually switch the switch to the corresponding setting based on the local mains voltage. If the switching setting does not match the actual mains voltage, it can directly damage the power supply and, in severe cases, may cause safety accidents. Another adaptation method is to use an active PFC boost circuit to achieve automatic voltage adaptation. While this circuit avoids manual switching, it requires dedicated control chips, boost inductors, MOSFETs, boost diodes, and other specialized components, significantly increasing the overall manufacturing cost of the power supply. This hinders its large-scale application in cost-sensitive computer power supply products. Therefore, existing computer power supplies struggle to achieve an effective balance between convenient voltage adaptation and cost control, leaving room for improvement. Utility Model Content

The relay drive unit (42) includes a transistor (421), a current-limiting resistor (422), and a freewheeling diode (423).

[0022] The connection relationships of each module and unit are as follows: In the standby voltage output module (1), the input terminal of the rectifier unit (11) is used to connect to the external AC voltage, the output terminal of the rectifier unit (11) is electrically connected to the input terminal of the filter unit (12), the output terminal of the filter unit (12) is electrically connected to the input terminal of the voltage regulator unit (13), the output terminal of the voltage regulator unit (13) serves as the output terminal of the standby voltage output module (1), and is electrically connected to one end of the filter module (5); the other end of the filter module (5) is electrically connected to the input terminal of the voltage regulator module (2), and the ground terminal of the filter module (5) is grounded; the output terminal of the voltage regulator module (2) is electrically connected to the power input terminal of the MCU control module (3), and the ground terminal of the voltage regulator module (2) is grounded.

[0023] The MCU control module (3) is equipped with a voltage detection pin and a control output pin.
