MICRO wholesale USB flash drive socket introduction Switching power supply mainly includes input grid filter, input rectifier filter, inverter, output rectifier filter, control circuit and protection circuit. Their functions are as follows. Input grid oscillator: Eliminate interference from the grid, such as the start of the motor, the on/off of the appliance, lightning strikes, etc., and also prevent the high-frequency noise generated by the switching power supply from spreading to the grid. Input rectifier filter: rectify and filter the input voltage of the grid to provide DC voltage to the converter.Inverter: It is a key part of the switching power supply. It converts the DC voltage into high-demand AC power: and 1 acts to isolate the output part from the input power grid. 
 
Wholesale Metal Keychain USB Flash Memory Drive: The metal keychain USB flash drive socket introduces the high-frequency AC voltage output from the converter to obtain the required DC voltage after rectifying and filtering. At 11 o'clock, it also prevents the interference of high-frequency noise on the negative wear.Control circuit: detect the output DC voltage and compare it with the reference voltage to amplify; modulate the pulse width of the oscillator to control the converter to keep the output voltage stable.Protection circuit: When the switching power supply has an overvoltage or overcurrent short circuit, the protection circuit makes the switching power supply stop working to protect the load and the power supply itself. The linear power supply generally samples the output voltage and sends it to the comparison voltage amplifier together with the reference voltage. The output of the voltage amplifier acts as the input of the voltage regulation tube to control the adjustment tube so that the junction voltage changes with the input change, thereby adjusting its The output voltage. However, the switching power supply changes the output voltage by changing the opening and closing time (ie, duty cycle) of the regulating tube.
