presents a comprehensive review of multilevel inverters (MLIs) for high-power microgridapplications. LIs have emerged as a pivotal techno ogy for efficiently converting DC to AC power in renewable energysystems and high- itor, and ca caded H-bridge configurations, highlighting their operational principles, advantages, andlimitations.
Advanced inverter technologies enhance the system efficiency, such as modular multilevel inverters with their storage capacity and cascade inverters with their novel switching capabilities. Despite benefits like reduced energy loss and minimized flicker, multilevel inverters are complex and costly due to their high number of switches.
For multilevel inverter configurations ranging from 3 levels to 35 levels, the THD values of the output voltage, calculated using all the methods, are presented in Table 7. The Half-Height (HH) Method yields the lowest THD value, demonstrating its superior effectiveness in harmonic reduction.
The output voltage of a two level inverter would comprise of two values (levels) with respect to the negative terminal of the capacitor, while the n -level inverter generates “ n ” voltage levels.
