描述:

Switching power supply is a device that rectifies the mains voltage and then forms pulses with a frequency characteristic of 10 kHz. The switching power supply differs from the ordinary not only in transforming and rectifying the input voltage by means of a diode bridge and smoothing capacitors, but also in converting the input voltage into relatively high-frequency pulses, in order to obtain quality rectified voltage, as close as possible to direct current.
