Switched capacitor based multi-level boost inverter for smart grid applications

To link DC power sources to an AC grid, converters are needed. Inverters the electronic devices, which used for this purpose. Conventional inverters employ harmonic filters and transformers that lossy expensive. Multilevel (MLIs) alternative conventional ones, proposing reduced total distortion (THD), increased range of control, inductor-less design. They generate a stepped waveform, with close similarity sine wave. Many distributed may be employed in smart grid. If those have minimal THD, filtering process could at point common coupling. This paper presents two switched capacitor based MLIs, boost capability low THD. inherent charge balancing capability, eliminates need auxiliary circuits voltage sensors. switches modulated using phase opposition disposition pulse-width modulation (PODPWM) method ease decrease losses switching. Designs were verified by simulation output waveforms introduced.
