There are many researches for the multilevel converters, but the researches are mainly for high voltage applications. However, multilevel converters are also attractive for under several kW converters. In the multilevel converters, there are so many power devices. So, an investigation of the power device loss is very important for an evaluation of the multilevel converters. This paper describes power devices loss of multilevel converters for several kW converters. First, the behavior of the typical multilevel converters is shown and analyzed for the selection of the main switching devices. And then, total devices loss including conduction loss and switching loss of the switching devices in the multilevel converters is investigated.
