FAQS 4

What is a DC inverter?

The word ‘inverter’ in the context of power-electronics denotes a class of power conversion (or power conditioning) circuits that operates from a dc voltage source or a dc current source and converts it into ac voltage or current. The ‘inverter’ does reverse of what ac-to-dc ‘converter’ does (refer to ac to dc converters).

What is a voltage source inverter?

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’.

What is an inverter ion?

ion to InvertersThe word ‘inverter’ in the context of power-electronics denotes a class of power conversion (or power conditioning) circuits that operates from a dc voltage source or a dc current source and converts it into ac vo tage or current. The inverter does reverse of what ac-to-dc converter does (refer to ac t

What is a current source type inverter?

Current source type inverters Current source type inverters control the output current. A large-value inductor is placed on the input DC line of the inverter in series. And the inverter acts as a current source. The inverter output needs to have characteristics of a voltage source.
