Abstract
In the present scenario to meet out the goal, multilevel inverter technology has introduced recently which helps to provide too much useful alternative in the field of huge power moderate range of voltage application. In this work an attempt has been made to study the complicated nature such as nonlinearities and chaos in cascaded multilevel dc to ac converter system. Cascaded multilevel H-bridge inverter has been taken and nonlinear behavior phenomena are observed using matlab/Simulink software package. It is reported that the dc to ac converter shifted their position from a stable operating condition to unstable operating condition as the bifurcation parameter like load varied for the power inverter system. Simulation results obtained through by software Matlab/Simulink demonstrate output voltage and current waveform of inverter along with its fftspectrum. This study for getting information about nonlinear behavior of power multilevel inverter system is playing very vital role for designing and fabrication of practical circuits in power electronics field.
