The reason why a switching power supply is called a switching power supply is that its core working principle is to quickly switch the switch state at a very high frequency by controlling the switching device (usually a transistor or MOSFET, etc.).
Specifically, these switching devices are constantly turned on and off, just like "on" and "off". When the switching device is turned on, the current can pass through and the energy is stored in components such as transformers or inductors; when the switching device is turned off, the stored energy is released and output to the load after a series of processing (such as rectification, filtering, etc.).
Through this fast switching action, the switching power supply can convert the input electrical energy into output electrical energy in different forms (such as different voltages, currents, etc.). In addition, by adjusting the time ratio of the switching device on and off (i.e., the duty cycle), the output voltage or current can be accurately controlled to maintain it at a stable set value.
Since its working process mainly revolves around the "on" and "off" of the switching device to achieve the conversion and regulation of electrical energy, it is vividly called a "switching power supply". This type of power supply has the advantages of being small, light, and highly efficient, so it is widely used in almost all electronic equipment, such as military equipment, industrial automation control, medical equipment, instrumentation, communication equipment, and other fields.
