Switching power supply is the use of electronic switch components such as transistors, field effect tube, silicon controlled rectifier thyratron, etc., through the control circuit, the electronic switch devices constantly “on” and “off”, make electronic switching device to pulse modulation of the input voltage, so as to realize the DC/AC, DC/DC voltage conversion, and output voltage harmonic voltage automatically.Switching power supply is generally composed of pulse width modulation switching power supply chip (PWM) control IC and MOSFET.Switching power supply chip refers to the pulse width control integrated power supply to adjust the output voltage and current stability.
Switching power supply can be divided into two major categories of AC/DC and DC/DC, DC/DC converter is modular, and design technology and production process in the most places have mature and standardized, and has been recognized by the user, but the AC/DC modular, due to its own features in the process of modular, the technique and technology of the complicated manufacturing problems.
With the development and innovation of power electronics technology, switching power supply is widely used in almost all electronic equipment with its characteristics of small size, light weight and high efficiency.Switching power supply chips are used in air purifier adapters, LCD chargers, communication equipment chargers, security monitoring chargers, digital products and instruments and other charger fields.
