Inverters and converters | Fuji Electric Global

In a broad sense, an inverter inputs alternating current with a constant voltage or frequency (for example, AC100V/50Hz or 60Hz supplied from a household outlet) and then converts it into different voltage and frequency before its output. Hence, it is different from the narrow meaning of "conversion from DC to AC", which may give rise to confusion.
