When it comes to designing and testing electrical and electronic equipment, having a consistently stable source of AC power is essential. A regulated electronic AC supply can solve power quality issues as well as provide additional testing flexibility.

This paper describes the use of AC power supplies for product testing. It will also discuss the use of regulated electronic AC power supplies to perform the various tests. General test examples are discussed as well as the parameters that are important to selecting an AC supply to perform them. Application examples are also provided.
