Abstract:
|
In this paper, a five-level multilevel-clamped multilevel
converter (5L-MLC2) topology is analyzed based on a typical
grid integration application for renewable energy system. The loss
and thermal distributions of the power devices in different switching
legs are investigated and illustrated under rated condition.
Afterward, a loss and efficiency evaluation method is proposed and
applied which takes into account various injected reactive power
ranges regulated by the grid codes. It is concluded that the loss and
thermal distributions of the 5L-MLC2 multilevel topology are unequal
between the clamping switching legs and the main switching
legs; it also shows a good and consistent efficiency characteristic
under different output power ranges when complying with the
grid codes. |
