What is an inverter?

An inverter is a device that converts direct current (DC) into alternating current (AC) power. Inverters are used in a variety of applications, from small devices such as portable fans and laptop chargers to large industrial systems.

There are two main types of inverters: those based on switch-mode power supplies (SMPS) and those based on conventional three-pulse or six-pulse thyristor circuits. SMPS-based inverters are more efficient than conventional inverters, but they are also more complex and more expensive.

Inverters are used in a variety of applications because they provide a convenient way to convert DC power into AC power. In many cases, AC power is more convenient than DC power because it can be easily transmitted over long distances without losing its strength.

Inverters are also used in applications where AC power is required but DC power is not available. For example, an inverter can be used to powering an AC load from a DC battery.

Inverters are available in a variety of sizes and power ratings. The size and power rating of an inverter must be matched to the application in which it will be used.
