Transformerless (TL) grid-connected photovoltaic (PV) inverters with a common-ground (CG) circuit architecture exhibit some excellent features in removing the leakage current concern and improving overall efficiency. However, ability to cope wide range of input voltage changes while maintaining output single power conversion stage is key technological challenge. Considering this, article at han...

Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...

Active networks (ANs) are a new paradigm in computer networking. In ANs, programs can be injected into routers and switches to extend the functionalities of the network. This allows programmers to enhance existing protocols and enables the rapid deployment of new protocols. Little work has been done in the area of multicast routing in heterogeneous environments. In this paper, we propose AMTree...

In this paper, a family of zero-voltage-transition (ZVT) magnetic coupling bidirectional DC/DC converters (BDCs) is proposed. The inductor has two functions: to serve as filter; and provide the auxiliary current. addition, phase-shifting control method used reduce conduction loss circuit. switches are all working under zero-current-switching (ZCS) conditions; thus, have no switching loss. Furth...

This article describes an enhanced switched capacitor cross-connected multilevel inverter (ESC3SMLI) with a machine learningbased model-predictive control method (ML-MPCM). The proposed ESC3SMLI produces nine levels using eight switches, including two bidirectional switching devices, single DC source, and capacitor.
