If the input dc is a voltage source, the inverter is called a voltage source inverter (VSI). One can similarly think of a current source inverter (CSI), where the input to the circuit is a current source. The VSI circuit has direct control over 'output (ac) voltage' whereas the CSI directly controls 'output (ac) current'.
DC Input: This is where the inverter connects to the DC power source. The power source could be solar panels, batteries, or other DC supplies. This component ensures that the inverter can receive electrical energy from these sources. Rectifier: In some inverters, a rectifier is essential, especially for converting AC to DC.
