“…While for high power applications multilevel inverters are the best alternative (or, sometimes, the unique), for medium or low power applications a controversy takes place. Experts on high frequency converters point out the compactness and reduced cost that can be achieved by employing high frequency switching [7,8]. On the other hand, experts on low frequency converters claim that the very best efficiency and robustness belong to the topologies based on low frequency [9,10].…”

This paper makes an analysis of the current demand on inverters for stand-alone renewable energy applications, and shows that reliability, surge power capability and efficiency are the most important aspects to be considered. It is shown that multilevel topologies can be very suitable for these applications due to their inherent high efficiency and robustness. In addition, it is shown that an optimized design must be in agreement with the typical load profile for stand-alone applications. A prototype of 3 kVA was implemented and it has proved itself to be robust. Peak efficiency of 96.0% was achieved: value that is higher than similar high performance inverters currently available in the market.
