摘要：
This paper proposes customization for a hybrid balancing scheme to reduce capacitor voltage ripple in a two-leg five-level neutral point clamped inverter. This customization introduces modulation changes in two regions of the hybrid balancing scheme. Following these changes, the active balancing control target options are re-evaluated to better suit the voltage ripple reduction objective. The paper outlines the backgrounds of changes and alternatives regarding the improvisation being adapted. Lastly, the applicability of the improvisations is demonstrated using a comparative Matlab-Simulink simulation of a two-leg five-level transistor clamped inverter under transient and steady-state conditions.
