Abstract: Switching Power Supply short Switching Power Supply (Switching Power Supply), due to power supply control function to adjust the regulator to switch devices that work consistently named. It is the use of modern power electronics technology, by controlling the switching-off time of the ratio of the output voltage to maintain a stable power supply, a small size, light weight, small power consumption, high efficiency, small ripple, low noise, intelligent a high degree of easy expansion and other excellent features, such as wider use of computers, color television sets, program-controlled switches, cameras, VCD, video games and other electronic devices. With the development of power electronics technology, especially high-power MOSFET and IGBT devices of the rapid development of the switching power supply will work to improve the high frequency levels to a high stability and cost-effective features, therefore, switches Power will gradually replace the use of the linear frequen
