Our common power sources, including power adapters and chargers, are all switching power supplies. The switching power supply is a power supply that maintains a stable output DC voltage by controlling the ratio of the time period in which the switching transistor is turned on and off. The switching power supply is generally composed of a pulse width modulation control IC and a MOSFET field effect transistor. The high frequency of switching power supply is the direction of its development. The high frequency makes the switching power supply miniaturized, and the switching power supply enters a wider range of applications, especially in the high-tech field, which promotes the miniaturization and lightness of high-tech products. Chemical. In addition, the development and application of switching power supplies are of great significance in terms of energy conservation, resource conservation and environmental protection.
