Technical FAQs 4

What is a DC link voltage?

M.J. Hossain The proper regulation of the DC link voltage is a crucial aspect of inverter operation, as the voltage level of the DC link, serving as an intermediary component between the DC source and the inverter, directly governs the output frequency and voltage of the inverter.

What is a multi-level inverter?

We can realize more sophisticated multi-level inverters that can directly synthesize more intermediate levels in an output waveform, facilitating nice harmonic cancelled output content. Example: Neutral-point clamped inverters (also called ”diode clamped” multi-level inverters).

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’.
