Abstract
Resonant modular multilevel converters (RMMCs)
have been proposed for high voltage dc-dc applications. Using dif-
ferent modulation strategies, RMMC operates in different modes
and achieves flexible step ratio. To provide a comprehensive study
of RMMCs, this paper presents the modulation method achieving
a wide range of step ratio with the ability of inherent-balancing.
The conditions for guaranteeing the inherent-balancing ability
are provided. The operation principle and performance of the
RMMC are presented in this paper, which have been explored
in a case study. The experimental results are obtained from a
bench-scale setup, which have verified the theoretical analysis.
