How Does an Inverter Work?

by Vaughnlea Leonard

A power inverter is a device that converts Direct Current (DC) to Alternating Current (AC) safely. Direct current is the type of electricity that works simultaneously to positive and negative electrical poles. For example, it is the type of electrical current found inside a battery. Alternating current, is the type of voltage found in the home. It flows back and forth between poles, rather than at the same time.

The two basic types of power inverters are either "modified" or "pure wave" sine. This simply refers to the type of repetitive wave output of an electronic signal--how it might look if it were visible to the naked eye. Modified inverters generally cost less than pure wave inverters. Pure wave inverters can generate the same level of power as your local electric company. Both inverters can operated a wide range of electrical equipment or household appliances.

To choose a power inverter, consider the size and how much money you want to spend. Be careful not to pick a significantly cheap inverter as it coulddestroy valuable electronic equipment. Cheaper inverters cause different voltages to skyrocket or "spike," causing irreparable damage to delicate circuitry. Resonance technology may be one way to improve future power inverter performance.
