In the recent times, modular multilevel converter (MMC) is a prominent choice of power electronic in medium voltage (MV)/high (HV) applications. The main features MMC are design, scalability, reliability, fault tolerance capability, high step-up ratio and less filtering requirements. This paper presents transformer-less based electric vehicle (EV) battery charger. A step-up/down dc-dc designed such that input converted to level. configuration ensures significant reduction complexity system...
This paper presents coordinated control scheme of electric vehicle charging stations (EVCSs) in smart transformer (ST) based microgrid. The microgrid is connected to the main grid through ST. Here, ST low voltage (LV) ac side converter operating on droop-control method. Battery energy storage system (BESS) and photovoltaic (PV) are LVac line droop-controlled converters. Two levels hierarchical structure have been implemented here: primary secondary control. EVCS at load bus used as...
The wireless power transfer (WPT) for electric vehicle (EV) charging has received significant attention due to several advantages, including ease of use, safety, low maintenance requirements, weather resistance, etc. This paper presents control, design, and prototype configuration resonant inductive LCL-LCL topology based WPT system. estimation values ratings components individual sections on the designed parameters are explained in detail. experimental results verify design show...
Distributed generations (DGs) and electric vehicle charging stations (EVCSs) are continuously increasing in the distribution system. These lead to voltage frequency violations, lower inertia, poor power quality, etc. Smart transformer (ST) with meshed network of lines is considered as an effective solution for improving performance, stability flexibility flow. However, it requires precise control converters. This paper analyzes performance autonomous decentralized virtual oscillator (VO)...
This paper presents a self balanced modular multilevel dc-dc converter (MMDC) based on the conventional buck topology, where both switches are replaced by capacitor clamped submodules (SMs). achieves significant reduction in input voltage through high-voltage step-down ratio, which is determined number of SMs. The phase shifted carrier pulse width modulation (PSC-PWM) technique used to control switching state SMs such that there constant supporting at any time. exhibits an inherent...
