With the rapid progress of the times,the clients have the higher and higher requirements for the quality of the switching power supply. The power supplies are asked to be passed the EMI,and the over-voltage,short circuit and over-temperature protection are must be needed.
But how do the power supplies get these function?
In the first,we need to know about the circuit composition of the power supply.
The main circuit of switching power supply is composed of input electromagnetic interference filter (EMI), rectifier filter circuit, power conversion circuit, PWM controller circuit, output rectifier filter circuit. The auxiliary circuit has the input over-voltage protection circuit, the output over-voltage protection circuit, the output over-current protection circuit, the output short-circuit protection circuit and so on.
As the professional manufacturer of the AC DC power supply and dc power supply,after we know the circuit composition of the power supply well,then we can make good power supply to satisfy you.
