    FAQs about Voltage Source Inverter Types

    What are the different types of inverters?

    Inverters are classified into many different categories based on the applied input source, connection wise, output voltage wise etc. In this article, we will see some of the categories. The inverter can be defined as the device which converts DC input supply into AC output where input may be a voltage source or current source.
