Abstract

This paper presents an unique three phase seven level inverter with reduced number of switches. Multilevel Inverters (MLI) are used in high power and high voltage applications as they are capable of producing multiple levels in output voltage with reduced THD. To reduce THD further, the number of levels in the output voltage has to be increased, which is directly associated with the number of switches required. To accomplish this, the conventional MLI experiences complexity in control, number of required DC sources, size, switching losses and cost of overall system increases. The proposed topology overcomes the aforesaid limitations and compared with the conventional MLI in terms of the number of switches, DC sources, capacitors, fundamental voltage, and THD. The performance is analyzed by using a simulation tool.
