A switching power supply is an electrical device that converts the incoming AC power from an outlet into DC power used by electronic devices. It uses a switching regulator to provide the desired output voltage and current at high efficiency. The switching power supply can be used in many applications, such as computers, consumer electronics, and industrial equipment.
Switching power supply is a modern power electronics technology which uses a pulse width modulation (PWM) control IC and MOSFETs to maintain a stable output voltage. Compared to linear power supplies, the cost increases faster with increase in output power, but with the development of power electronics technology, the cost of reversal point moves to the lower end of the output power, providing a broad space for development.
High-frequency switching power supply in the direction of its development , so that high-frequency switching power supply miniaturization and make switching power supply into a wider range of applications, especially in high-tech fields, to promote high-tech products of the small , lightweight technology . Also switching power supply in the development and application of energy conservation , resource conservation and environmental protection aspects are of great significance .
The application of the switching power supply of power electronic devices are diode , IGBT ( insulated gate bipolar transistor ) and MOSFET.
SCR rectifier circuit in the switching power supply input and soft-start circuit has a small amount of application , GTR driver difficulties , the switching frequency is low, gradually being replaced by IGBT and MOSFET .
Switching power supply of the three conditions
1, the switch: power electronic devices work in the off state, rather than linear state
2 , HF: high frequency power electronic devices operating in the frequency rather than close to the low-frequency
3 , DC : switching power supply output is a DC rather than AC
