Abstract :
In this paper, a generalized space vector modulation technique is used for the control of a three-phase, neutral-point clamped converter in both rectification as well as inversion modes. The SVPWM can be extended to higher-level converters. A simple control algorithm is used for the balance of DC-bus capacitor voltages by identifying the unbalance generated by different conduction states and using a very simple method to achieve balanced capacitor voltages by using the redundant switching vectors. The analytical study is validated by the simulation results of the converter.
