About this Course
Uninterruptible power supplies (UPS) provide backup power on loss of main power to a system. The UPS is sometimes called a switching power supply and differs from a backup system, such as a diesel, in that it provides instantaneous switchover on loss of power. The principles of operation are the same whether backing up a desktop computer or a large power system.
By the end of this course, you will be able to:
- Describe the operation of the power switching circuit
- Explain the basic operation of a rectifier circuit
- Explain the operation of the battery charger circuit
