Vector Modulation

A single-juncture topology of 3-Ø boost inverter with riven DC supply configuration grieves from larger incidence current commutations across the diodepassive in connection with the DC source and the intricate study as the inductor charges with capricious duty cycle. This study focuses on 1-Ø riven bias inverter with improvised technique on inverter and modulation. The riven bias inverter is analyzed using state space averaging technique to derive the mathematical model that is suitable for both steady-state and dynamic behavior conditions considering main converter nonlinearities. Hence, the research is carry forwarded in modeling the riven bias inverter on DC section with digital space vector modulation control technique to obtain decoupled control structure in lattice network and the work is validated by means of MATLAB/SIMULINK.

The Impact

In this research, a new space vector modulation control algorithm is proposed to increase the reliability of the cascaded H-bridge multilevel inverters in case of faulty situations, where one or several power cells do not function. Methods to detect faults ensure finding open-circuit module exactly, which is fast and easy to program. By giving a detailed analysis of the impact of the faulty power cells, optimal redundant level states are chosen such that highest possible output voltage can be achieved, while the balance of the three-phase line-to-line voltage is maintained and common-mode voltage is reduced. The proposed algorithm is generalized so that it can be applied to H-bridge inverters of any level. The validity of the method is verified by numerical simulations and experiment results with an 11-level cascaded H-bridge inverter.
