| Abstract |
In this paper a new snubber circuit design for
three-level inverter will be presented. The so-called “Dual
snubber Circuit” still comprises most of the positive features
as a low number of components, improved efficiency due to
the low snubber element and power semiconductor losses,
reduced over-voltage across the semiconductor devices and
no balancing problems. With these advantages, the new
dual-use snubber circuit can be used for high power
inverters as well as the so-called Flexible AC Transmission
Systems (FACTS). The presented snubber circuit has been
analyzed and confronted with different existing converter
designs using a simulation environment. The simulation
results are compared with the output of a standardized
three level converter system to verify the advantages of the
new snubber design. |
