| Popis: | Cascaded H –Bridge (CHB) is one of the multilevel inverter topologies which is most used in the medium and high-powerapplications.To increase the output power and the voltage levels hybrid cascaded H bridges with unequal input voltages have been proposed in the various publications. The number of stages i.e. series connected H -bridges are reduced.It also reduces the distortion and the Electromagnetic Interferences (EMI). The analysis of the hybrid Cascaded H bridges operated with level Shifted (LSPWM), Phase shifted (PSPWM) and Nearest Level Control (NLC) have been studied. Total Harmonic Distortion (THD), fundamental output voltage and the first harmonic spectrumare the performance parameters considered. The comprehensive simulations of three stage CHB, and new hybrid multi-level inverter topologieshave been carried out in MATLAB/SIMULINK software. |
