What is an Inverter?

An inverter is a power conversion device that uses semiconductors.
A device that converts direct current to alternating current is called a DC-AC inverter.
In general, a circuit that converts a specified frequency and voltage by combining an AC-DC converter and a DC-AC inverter, is called an inverter circuit (inverter).
It realizes a wide range of rotation speeds with high efficiency drive and smooth rotation.
Since the output voltage and the output frequency can be controlled arbitrarily, it is widely used for controlling the rotation speed for AC motors and brushless motors. Invertor control achieves low power consumption and high efficiency drive.
