Abstract：HOW DO INVERTERS CONVERT DC ELECTRICITY TO AC?
One of the most significant battles of the 19th century was
fought not over land or resources but to establish the type of electricity that powers our buildings.
At the very end of the
1800s, American electrical pioneer Thomas Edison (1847–1931) went out of his
way to demonstrate that direct current (DC) was a better way to supply
electrical power than alternating current (AC), a system backed by his
Serbian-born arch-rival Nikola Tesla (1856–1943). Edison tried all kinds of
devious ways to convince people that AC was too dangerous, from electrocuting
an elephant to (rather cunningly) supporting the use of AC in the electric
chair for administering the death penalty. Even so, Tesla's system won the day
and the world has pretty much run on AC power ever since.
The only trouble is, though
many of our appliances are designed to work with AC, small-scale power
generators often produce DC. That means if you want to run something like an
AC-powered gadget from a DC car battery in a mobile home, you need a device
that will convert DC to AC—an inverter, as
it's called. Let's take a closer look at these gadgets and find out how they
