Abstract
In this paper a five-level Multi-Clamped
Multilevel Converter (5L-MLC2) topology is analyzed based on
a typical grid integration application for renewable energy
system. The loss and thermal distribution of the power devices
in different switching legs are investigated and illustrated
under rated condition. Afterwards, a loss and efficiency
evaluation method is proposed and applied which take into
account various injected reactive power ranges regulated by
the grid codes. It is concluded that the loss and thermal
distribution of 5L-MLC2 multilevel topology is 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.
