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.
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.
This study provides a comprehensive analysis of multilevel inverter systems that are wired into the main power supply. Grid-connected inverter types and their configurations are discussed in depth in this review.
Grid connected multilevel inverter (GCMLI) topologies Recently, the grid connected multilevel inverters (GCMLIs) have become popular when used in conjunction with renewable energy sources (Jana et al., 2016). The GCMLI topologies are broadly classified as traditional MLIs and reduced switch MLIs.
Multilevel Inverter: The multilevel inverter converts the DC power from the PV array into AC power with reduced Total Harmonic Distortion (THD). By generating a smoother AC output with multiple voltage levels, it improves power quality, especially in grid-connected systems.
