Abstract
In this paper a nine level Z-packed U-cell (ZPUC9) multilevel converter has been proposed as a submodule of modular multilevel converter (MMC) to increase the voltage level at the output waveform. Single DC source ZPUC9-MMC generates 17-level phase voltage and 33-Level line voltage waveform through single submodule per arm which increases the voltage quality owing to total harmonic distortion (THD) reduction and increase the reliability due to reduced counts of devices. Single DC source operation for single-phase and three-phase operation as well as the modularity is the main advantages of proposed configuration in comparison with the counterpart converters. Voltage balancing integrated with modulation technique has been used to control and regulate the flying capacitors (FCs) voltages of the converter. Simulation results obtained by MATLAB-Simulink validate the performance of proposed converter in transient and steady state in stand-alone mode
