| Abstract |
This paper presents a new method to balance the
DC link voltages in a 3 level Diode Clamped Rectifier, even
in the presence of unbalanced loads which cause a non-zero
neutral point current. The method employs an offset which
is added to each of the inverter modulation waves. This
offset causes a zero sequence voltage which can drive the
desired neutral point current whilst maintaining balanced
DC link voltages. Simulation and experimental results
confirm the method. |
