Question
The line-interactive type of these devices regulates utility voltage before the voltage passes through any equipment. For 10 points each:
[10m] Name these devices that protect against power interruption to allow for graceful shutdown or for operation to continue until a generator comes online.
ANSWER: UPSs [or uninterruptible power supply or uninterruptible power supplies or uninterruptible power sources; prompt on power supply or power supplies or power sources]
[10e] Line-interactive UPSs use one of these components equipped with a tap changer. These components use paired windings to adjust the voltage of alternating current.
ANSWER: transformers
[10h] Line-interactive UPSs always have one of these components connected, though sometimes in reverse. The three-phase type of these components can be built using a full bridge configuration containing three pairs of switches, with one switch in each pair conducting for 180 degrees at a time.
ANSWER: inverters [or power inverters]
