Asymetrical Multilevel Hybrid Inverter - Analysis And Experimentation

New Hybrid Cascaded Multilevel Inverter

This paper proposes a single-phase five-level inverter with a modified pulse width-modulated (PWM)control scheme. The modified pulse width-modulation technique is developed to reduce switching loss.Also, the proposed multilevel inverter can reduce the requirement of power switches compared to aconventional cascaded multilevel inverter. The modes of operation, control signals, and operatingprinc...

Hybrid Multilevel Inverter using ISPWM Technique for Fuel Cell Applications

Fuel cells have been considered as the primary energy source for the distributed power generation as they are highly efficient, modular and clean. The main drawback is that the dc voltage generated by a single fuel cell varies from 0.7V to 1V. Due to the low input voltage in fuel cells, a suitable power conditioner is required to interface to the utility grid or local loads. To meet this requir...

New Hybrid 27 Level Multilevel Inverter fed Induction Motor Drive

This paper deals with new hybrid multilevel inverter fed induction motor drive. It focuses on asymmetrical topologies, the general function of this multi level inverter is to synthesize a desired voltage from several separate dc source. This hybrid topology has more advantageous of industrial applications. In conventional methods, the need of converters to supply the cells of reversible multile...
