[0002] An inverter is a converter that transforms direct current (DC) power (from batteries or storage batteries) into alternating current (AC) power (typically 220V, 50Hz sine wave) with fixed frequency and voltage or adjustable frequency and voltage. For example, when working or traveling, an inverter can be used to connect a storage battery to power electrical appliances and various tools. Inverters are also widely used in photovoltaic power plants for power transmission. In simple terms, an inverter is a device that converts direct current (DC) into alternating current (AC).
