Power inverters are devices which can convert electrical energy of DC form into that of AC. They
come in all shapes and sizes, from low power functions such as powering a car radio to that of backing
up a building in case of power outage. Inverters can come in many different varieties, differing in price,
power, efficiency and purpose. The purpose of a DC/AC power inverter is typically to take DC power
supplied by a battery, such as a 12 volt car battery, and transform it into a 120 volt AC power source
operating at 60 Hz, emulating the power available at an ordinary household electrical outlet.
