info@upspowersupply.netDifference between Redundant Power Supply and UPS
In redundant cold standby, the power supply consists of several modules
with same function. Under normal conditions, one module supplies power;
When it gets faulty, the standby module starts immediately to work. Such
a mode would cause a switching time between batteries, thus leaving a
voltage gap.
In the paralleled current sharing N+1 standby mode, the power supply consists of several identical units that are connected in parallel through joint gate diodes, all units supply power to the device at a same time. In redundant hot standby, the power supply consists of several units that work at a same time, but only one unit supplies power to the device, others bear no load. When the main power supply fails, the standby power supply can put in use immediately, the output voltage fluctuates slightly.
UPS is an important external device that can provide continuous, stable and uninterrupted power supply. According to the working principle, it can be divided into three categories: standby UPS, online UPS and online interactive UPS. UPS is similar to such a machine, which can maintain power supply for a period of time when the commercial power supply stops, so that people have time to save data and then shut down the machine calmly.
For some systems that require long-term uninterrupted operation and high reliability, such as base station communication equipment, server, they generally require high reliable power supply. Redundant power supply design is one of the key parts and plays an important role in high availability system. It’s usually equipped with 2 or more power supplies. When one power supply goes wrong, other power supplies can be put into operation immediately without interrupting the normal operation of equipment. It’s similar to the principle of UPS: when the commercial power supply disconnects, the battery supplies power instead. The main difference between redundant power supply and UPS is that it’s supplied with different powers simultaneously, but UPS supplies power with one battery while keeping another standby, they switch automatically if necessary.
Connection of traditional redundant power supply
In the design scheme of traditional redundant power supply, it connects with diode anode through 2 or more power supplies respectively, and then outputs in parallel to power bus in the way of joint gate. It can make one power supply to work independently, or make several power supplies to work at the same time. When one power supply gets fault, the output of power bus would not be affected due to the one-way electric conduction of diode.
