Regulated Power Supply Circuits

Hot swap structure offers improved redundancy: 01/09/03  EDN-Design Ideas / For redundancy purposes, a number of power supplies, using ORing diodes, can work into the same load. During maintenance, when you can remove any power supply, the minimum possible power perturbation at the load is desirable. To compensate for the voltage drop across the ORing diodes, you must connect the power-supply feedback lines after the diodes, at the load.
