Due to the advantages of power supply systems using DC distribution method, such as a conversion efficiency increase about 5–10%, cost reduction 15–20%, etc., AC will be replaced by in future. This paper adopts different converters generate system: DC/DC converter with PV arrays, factor correction utility line and full-bridge multiple input sources. With this approach, proposed soft-switching f...

Modular Multilevel Converter (MMC) is an emerging converter topology for medium and high voltage applications. Nearest level Modulation (NLM) the conventional control used to MMC that produces N+1 AC output waveform. In previous research work, Modified NLM has been already proposed, producing a 2N+1 4N+1 waveform while utilizing half-bridge (HB) submodule (SM) topology. However, half-bridge-bas...

The most popular DC-DC converter topologies are also the simplest the flyback converter and the forward converter. Much of their simplicity is because they employ a single power transistor referenced to the primary-side return. Though these topologies are straightforward, they do have some significant drawbacks in many applications. In these situations, designers turn to more elegant topologies...

In this paper, topology of a Grid connected solar microinverter is proposed. The DC power obtained from the solar panel is converted into a rectified AC signal. This conversion is realized by an Active Clamped Flyback Converter. A full-bridge inverter which switched at a high frequency converts this rectified AC into sinusoidal AC of power frequency and this also controls the power flow directi...

Recently, the integrated On-Board Charger (OBC) combining an OBC converter with a Low-Voltage DC/DC Converter (LDC) has been considered to reduce size, weight and cost of DC-DC converters in EV system. This paper proposes new V2G (Vehicle-to-Grid) auxiliary battery charge functions. In proposed converter, is composed bidirectional full-bridge active clamp circuit hybrid LDC Phase-Shift Full-Bri...

This paper deals single phase 27-level multilevel inverter topology for DER’s-based DC/AC conversion system. This work mainly focuses on cascaded MLI using three unequal dc sources in order to produce twenty seven-level output. In this study, a high step-up converter is introduced as a front-end stage to improve the conversion efficiency of conventional boost converters and to stabilize the out...
