This paper presents a converter consisting of a dual active bridge built upon three-level neutral-point-clamped legs in order to synthesize a five-level medium- or high- frequency stepped waveform on… (More)
Aiming to improve the performance features of conventional two-level dual-active-bridge (DAB) converters, this paper presents a three-level neutral-point-clamped (NPC) DAB dc-dc converter. A general… (More)
This paper proposes a modulation strategy for multilevel multiphase diode-clamped dc–ac converters (also applicable to other functionally equivalent topologies) able to keep the dc-link capacitor… (More)

This paper presents an efficiency analysis of a recently-published topology, the multilevel-active-clamped (MAC) topology. In order to assess the MAC topology, an efficiency comparison between a… (More)
This paper proposes and demonstrates the feasibility of a dual-active-bridge converter built upon four-level active-clamped legs. A suitable modulation pattern is defined. The dc-link capacitor… (More)
