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...
An effective approach on zero-voltage switching scheme for a single-stage grid-connected flyback inverter along with the introduction of Modified Grey Wolf Optimizer technique based proportional integral controller is proposed. A focus soft-switching attained by means permitting grid-side negative current bidirectional switches held in transformer’s secondary side. Consequently, there discharge...
In this paper, a multi-port non-isolated SEPIC converter is analysed for integrating with the renewable energy source and also losses efficiency are calculated. The proposed utilizes single stage power conversion, thereby providing higher efficiency. structure comprises of combination Pulsating Voltage Cells (PVC) Source Cell (PVSC) on input side Load (PVLC) output side. two topologies involved...
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. Additionally, the design generates negative level without use of extra circuitr...
A bidirectional multi-resonant DC/DC converter is proposed in this study. The structure of the symmetrical, and operating characteristics operation mode are same. Adopting synchronous driving, can regulate output voltage over a wide range. Regardless forward or reverse mode, switches realise zero-voltage switching entire gain be zero due to its similar notch filtre. transmit fundamental wave th...
This paper proposes a high-frequency isolated current-fed dual active bridge bidirectional DC–DC series resonant converter with an inductive filter for energy storage applications, and steady-state analysis of the is carried out. The performance proposed has been compared voltage-fed capacitive output filter. topology operated in continuous conduction mode zero circulation current (ZCC), less s...
This paper presents a single-phase transformerless bidirectional power factor corrector (PFC). A capacitor is inserted into conventional full-bridge PFC by connecting the ac line terminal and of DC voltage. The functions this have two roles: to bypass common-mode leakage current from stray capacitor; form an LCL filter reduce inductor ripple. hybrid modulation method employed in PFC. unipolar s...
