Abstract: Three phase multilevel inverters are frequently utilized in moderate and high power industries by minimizing the electromagnetic interference (EMI), enhancing the voltage profile and improving the power capacity. Although various converter topologies are developed for multilevel inverters (MLIs), Z-source MLIs are widely used for higher voltage applications. Z-source MLIs diminishes the total harmonic distortion (THD), and it has good stability and efficacy for various electrical power system applications. This paper aims to develop a three phase Z-source seven-level cascaded H-bridge (CHB) inverter with multicarrier PWM control techniques. The Z-source CHB inverter with multicarrier PWM control is modeled and its performance investigation with shoot through and non-shoot through modes is carried out in MATLAB/Simulink software platform.
Keywords: Buck-boost, CHB inverter, Multicarrier pulse width modulation, Total harmonic distortion, Z-source network.
