Highlights and Novelties
1-This topology of input switched multilevel converter is not suitable for high voltage power applications due to the fact that the power devices of the High Bridge need to stand a voltage rating of dc link voltage.
2-Solar photovoltaic converters continue to be one of the most active research areas, both for grid connected and standalone applications.
3-In this paper a new Space vector pulse width modulation control strategy for an input switched multilevel converter topology which treats the multilevel converter as a two level converter is proposed to modulate the output voltages allowing simple implementation.
4-The process to search for the different combination with smallest remaining reference vector by the smallest hexagon in the space vector diagram.
5-This topology of input switched multilevel converter is simulated and modeled nine levels multilevel inverter using matlab Simulink model with hardware implementation.
This paper introduces a new Space Vector Pulse Width Modulation (SVPWM) approach for a hybrid input switched nine level converter for a three phase photo voltaic energy generation systems. The multilevel converter topology is a cascaded connection of input switched and H-bridge converters, which can provide 2N+1 voltage levels for each phase. The proposed SVPWM strategy treats the multilevel converter as a two-level converter by introducing a new offset vector approach. With the generated switching pattern, it is possible to get a minimum number of switching-state transitions and switch the H-bridge close to line frequency; thus, the switching losses can be considerably reduced with minimum level. The proposed SVPWM approach has been applied in a nine level converter to express the principle of operation. The advantages of the proposed scheme and designs are demonstrated by both simulation and experimental results.
