A New Transistor Clamped 5-Level H-Bridge Multilevel Inverter with voltage Boosting Capacity ABSTRACT Multilevel converters offer high power capability, resulting with lower output harmonics and lower commutation losses. Their main disadvantage is their complexity, requiring a great number of power devices and passive components, and a rather complex control circuitry. This paper presents a new topology of the multilevel inverter with feature like output voltage boosting capability along with capacitor voltage balancing. The proposed multilevel inverter uses transistor clamped H-bridge (TCHB) with an bidirectional switch and four auxillary switches producing a boost output voltage . The single unit of new topology produces five-level output with output voltage double the input DC voltage where as a single unit of conventional H-bridge produces three-level output voltage similar to input DC voltage. The comparison has made between the proposed five-level inverter and conventional cascaded five-level inverter in terms of the output voltage , total harmonic distortion (THD) , No. of switching devices used etc. The analysis of the output voltage harmonics is carried out and compared with conventional cascaded H-bridge inverter topology. In this paper the new configuration of the (symmetrical H-bridge) single phase 5-level inverter is proposed which produces a five-level output voltage instead of three-level as in case of conventional H-bridge. Also this new proposed topology produces the boost output voltage in comparison to conventional H-bridge topology which requires two H-bridge cells producing the five-level output voltage but the output voltage equal to the input DC voltage.
