One Circuit Design for Suppressing Surge Current of Switching Power Supply

Abstract:

Based on the analysis of the causes for surge current of switching power supply and its harm, a circuit design suppressing surge current, which uses NMOSFET as the second switch , is represented in this paper. Test results show that: the method can suppress the surge current to a large extent and reduce the impacts on equipments. Due to improving the safety and the reliability of equipments, this circuit design is more popular in circuit design for suppressing surge current of switching power supply.
