Popular science on the working principle of switching power supply module
Switching power supply module is a common power supply device that works by converting input voltage into high-frequency alternating current and then converting it into the required output voltage. This working principle enables the switching power supply module to efficiently convert electrical energy while also providing a stable output voltage.
The working principle of the switching power supply module mainly includes the following steps: First, after the input voltage is rectified and filtered, it enters the input end of the switching power supply module. Then, through the action of the switching tube and transformer inside the switching power supply module, the input voltage is converted into high-frequency alternating current. Then, the high-frequency alternating current is rectified and filtered, and then passes through the voltage stabilizing circuit to finally output the required stable voltage.
In this process, the switching action of the switch tube controls the conversion of the input voltage and the stability of the output voltage, while the transformer plays the role of voltage conversion. The voltage stabilizing circuit ensures the stability of the output voltage, thereby ensuring that the output of the switching power supply module can meet the power needs of various devices.
In general, the working principle of the switching power supply module is to efficiently convert the input voltage, and through a series of circuit controls and transformations, finally output the required stable voltage. This working principle makes the switching power supply module an indispensable power supply device in various electronic equipment, and also provides an important guarantee for the stable operation of electronic equipment.
