Multilevel inverter technology has emerged recently as a very important alternative in the area of high-power medium-voltage energy control. This paper presents the most important topologies like diode-clamped inverter (neutral-point clamped), capacitor-clamped (flying capacitor), and cascaded multicell with separate dc sources. Emerging topologies like asymmetric hybrid cells and soft-switched...

This article presents detailed Markov models for the reliability assessment of multilevel neutral-point-clamped (NPC) converter leg topologies, incorporating their inherent fault-tolerance under open-circuit switch faults. The are generated and discussed in detail three-level four-level active NPC (ANPC) cases, while presented methodology can be applied to easily generate a higher number levels...

DC-DC boost converters are mostly employed in renewable energy system such as photovoltaic system, fuel cell and so on, because these systems generate low output voltage which is not suitable for grid connected power applications. This paper proposes an interleaved boost converter which consists of voltage doubler cell and clamped circuit to achieve large output voltage gain without extremely i...

A technology has been demonstrated that uses compression bonding to modularly combine platform-supported μmechanical filters with integrated BiCMOS transistor circuits while attempting to preserve the Q of mounted resonators. In this process, μmechanical devices are first fabricated onto SOI platforms, which are then released (together with devices) and compression bonded onto a transistor circ...

This paper summarizes the multilevel power conversion technologies published in the IEEJ Transactions on Industry Applications and presented at IEEJ Technical Meetings on Semiconductor Power Converter or Japan Industry Applications Society Conferences (JIASC) as well as international conference proceedings and journals. This survey includes various types of circuit topologies from the first neu...

Arrays of clamped active filaments, interacting via steric forces, display traveling waves and jammed clusters.

-In this paper, comparative evaluation of different techniques for harmonic reduction in input current of ac-dc converter is presented. Converters employing ac side switching, resonant converter, active clamped boost converter are simulated in PSIM and their performance under varying load condition with load voltage regulation is evaluated. The results revealed that active clamped boost convert...

This article proposes a novel device designated as an intelligent electronic fuse (iFuse) intended to be connected in series with any current-bidirectional voltage-unidirectional active switch present power converter. The iFuse duty is selectively isolate its series-associated from the rest of converter circuit immediately after detecting that this has failed short circuit. Nonetheless, it main...
