Redundant Power Supply Design

Fault in one phase of the primary power supply 1 power supply units connected in parallel are operated on separate phases.

Redundant power supply design.

The independence of alternative parts comprising a redundant system can never be absolute and total unless they are completely separate and autonomous from supply up to the final user including the respective control systems. The redundant power supply is important for servers and other highly important computers to minimize the chance of a complete computer shutdown or failure. In this way if one phase fails or malfunctions the supply of power is not affected. Such as using two power supplies connected to the same socket in such a way that if one power supply failed the other would too.

Redundant power techniques for servers high availability system power supplies are bused in or n 1 configurations or a combination of the two. Examples of redundant power supply configurations for server applications are discussed. Highly specialized for design of lv mv switchgears and lv high power busbar trunking 6300a in power substations. In all other cases there are contact points both for power circuits and for protection and control systems.

Common redundant power supply. Load sharing is achieved through careful power bus design. The system shown in figure 2 two out of the three components are required for the system to function and there is one redundant component. Redundant power supply configuration are described below including suitable solutions figure 1.

The extra strength used in the design is called the margin of safety.
