| Abstract |
This paper presents the modelling, analysis and
control of a three-level PWM rectifier working
with vector modulation. Specifically, this paper
identifies the unbalance generated by the
different conduction states and proposes a very
simple method to achieve balanced capacitor
voltages by using the redundant vectors in the
modulation, depending on the polarity of the
voltage difference and the direction of power
flow. Simulation results confirm the conclusions
of the analytical study. |
