METHOD AND ARRANGEMENT FOR REDUCING IN-RUSH CURRENT OF MULTI-MODULE SYSTEM

摘要

A method and an arrangement for reducing in-rush current of a multi-module system are provided. The system comprises a plurality of modules designed to perform predefined functions; a power supply unit designed to provide power to the plurality of modules. Each of the plurality of modules comprises a power control system which performs a respective time delay on the power-on of the power received from the power supply unit. With the system and the method, the total in-rush current of the multi-module system is greatly reduced.
