Abstract
In this paper, we proposes a multilevel inverter which can synthesize multi output voltage levels by adding DC voltage sources and switch components. In the proposed circuit topology, full-bride inverter determines the output polarity and the number of output voltage levels are defined by the operation of the additional switches. It can reduce the number of switch devices compared with the conventional approaches when they generate the same number of output voltage levels. To verify the validity of the proposed multilevel inverter, we present simulation and experimental results using a prototype.
