An inverter refers to a power electronic device that converts power in DC form to AC form at the required frequency and voltage output. Inverters are classified into two main categories −
Voltage Source Inverter (VSI) − The voltage source inverter has stiff DC source voltage that is the DC voltage has limited or zero impedance at the inverter input terminals.
Current Source Inverter (CSI) − A current source inverter is supplied with a variable current from a DC source that has high impedance. The resulting current waves are not influenced by the load.
