FAQs 6
Can a multi-level inverter have multiple DC link voltage sources?
Several multi-level inverters with multiple DC link voltage sources like PV sources have been discussed in Section 3.2. In a CHB based GCMLI, as all of the H-bridges share the same amount of grid current, it is a necessity to implement a unique grid current control loop.
Are two-level inverters suitable for a utility grid?
Conventional two-level inverters when used as an interface between PV sources and the grid (Myrzik, 2001, Kjaer et al., 2005) were found unsuitable for the medium and high voltage utility grid due to a smaller number of output voltage levels (Colak et al., 2011a) and hence, greater harmonics in the injected grid current.
