An inverter is a device that can variably control the voltage and frequency of AC current. Generally, the AC current supplied from a power source has a constant voltage and frequency, which is standardized by the country. In order to change the voltage and frequency of the AC current to any desired value, it is necessary to convert the AC (alternating current) electricity to DC (direct current) and then back to AC (alternating current). In this case, an inverter is needed.

The semiconductor devices used in inverters are called power devices. Among the power devices, IGBTs using SiC and MOS-FETs using GaN and GaO are the most common switching devices. These are characterized by high withstand voltage and are suitable for use under high current.

Inverter drive is a method of controlling machinery by changing the voltage and frequency using an inverter. Inverter drives include the motors of air conditioners and washing machines, the drive motors of railroad cars (trains), electric vehicles (EVs), hybrid vehicles (HVs), and plug-in hybrid vehicles (PHVs). In particular, railroad cars and hybrid vehicles can utilize regenerative energy from regenerative braking, which is attracting attention as a highly energy-efficient drive system.
