Expert Solution & Answer
Chapter 9, Problem 17RQ
Explanation of Solution
UPS systems:
The full form of UPS is “Uninterruptable Power Supply”. They act as a backup power supply for computers. The powering capacity of UPS is usually measured in volt-ampere. A normal computer uses 200 VA and during interruptions or power fluctuations, it gets efficient power supply from UPS which provides up to 1,000 VA.
Types of UPS:
There are four primary types of UPS. They are as follows:
- Standby UPS
- Standby ferroresonant UPS
- Line-interactive UPS
- Double conversion online UPS
| Types of UPS | Definition | Advantages | Disadvantages |
| Standby UPS | It is also called as offline UPS. This UPS finds out the fluctuations and feeds its battery power through inverter. | It is low in cost, efficient. | It has poor output voltage regulation and it has minimal voltage protection. |
| Standby ferroresonant UPS |
Though it overcomes standby UPS system, it is also an offline UPS. The updated part is that it replaces the transfer switch. It provides power via electrical service and it uses UPS as the battery backup... |
