Design of surge suppression soft start module for switching power supply
The switching power supply will produce a large surge current at the moment of connection,which is easy to cause the input fuse to burn,the closing switch contact to burn out or overcurrent damage to the rectifi-er,resulting in the malfunction of the power supply.To address the surge current issue in switching power sup-plies,a surge suppression soft start module is designed.This module adopts an intelligent segmented charging method,which can suppress instantaneous surge currents below 200A during high voltage input,without affecting subsequent circuits after startup.This design can not only ensure reliable operation and reduce failure rates of the power supply but also extend its service life,which has certain promotion value.
