According to the "international safety system power engineering specification", the state stipulates that spare power, such as batteries and power supplies, need parallel. The reason is that one node in the series circuit is broken and the whole system will be paralyzed. This is the basic common sense of physics. In parallel, one of them is broken and the other is good, so the advantage of the backup power is that it can really play a backup role.

Even multi loop parallel and monitoring, so as to ensure complete. This is a principle to: parallel circuit roads when problems arise, a cut in the throat, each line has no limbs parallel alternate effect. And if the multi loop parallel and monitoring, that is the equivalent of each line is actually independent, there is no direct relationship between 22. In this case, even if the road is a parallel problem in another line of the alternate effect.

To sum up, the standby power supply is in parallel, and it is necessary to parallel the multiple circuits.
