Inve1 ter Also called the switching section or engine, this is the pait of the
unit that inve1ts DC cunent to AC cmTent.
IP Internet protocol
Lagging CmTent follows, or lags, voltage in an inductor. A source
producing power with a lagging power factor reduces the utility
grid voltage.
Leading
CmTent leads the voltage in a capacitor. A source producing
power with a leading power factor increases the giid voltage.
