Using VFCB PWM Method Multilevel Inverter Balancing Switching Transitions
Authors(3) :-N. Kamalakannan, A. Arulvizhi, J. Jayashree
A multi-level PWM technique has been developed to reduce the lower order harmonic distortion. The implementation of the existing control strategies has been found to affect the switch utilization and increase the losses. The Variable Frequency Carrier Band (VFCB) has been found to equalize the number of switching at all levels and contributes to reducing the losses besides allowing uniform dissipation of power in the switching devices. The existing SHPWM methods create inferior harmonic spectrum and unequal utilization of devices. Therefore, a new Pulse Width Modulation (PWM) strategy, with the view to ensure that the power devices at all the levels are switched equal number of times is proposed in this paper. The MATLAB-based simulation response and its experimental validation are included to highlight the fact that there is a significant enhancement in harmonic power distribution besides contributing to reduce the switching losses and improve the efficiency.
