Multi-port DC-DC converter has attracted special interest in applications where multiple energy sources are used. In this project, a three-port converter with three active full bridges, two LCC resonant tanks, and a three-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load, and a renewable source such as...

The paper focuses on a DC/DC converter that is used to adapt a varying output voltage from a solar panel to demands of an electrolyzer unit or battery charging purposes. The converter covers an input voltage span from 9 V to 24 V and has an output voltage of 12 V at a maximum current of 50 A. A modular topology of the converter is described along with a microcontroller control strategy. Finally...

This Paper introduces new hybrid converter topologies which can supply simultaneously AC as well as DC from a single DC source. The new Hybrid Converter is derived from the single switch controlled Boost converter by replacing the controlled switch with voltage source inverter (VSI). This new hybrid converter has the advantages like reduced number of switches as compared with conventional desig...

In this paper an efficient topology of (Single Ended Primary Inductor Converter) SEPIC/Zeta converter is proposed to interface renewable energy sources and the load. The proposed converter is obtained by the integration of the bidirectional converter and the full-bridge converter. As the output voltage of the proposed converter is not reversed this topology provides remarkable advantages than t...

This paper proposes a novel wind energy conversion system based on a Five-phase Permanent Magnetic Synchronous Generator (5-PMSG) and a Five to three Matrix Converter (5-3MC). The low cost and volume and also eliminating grid side converter controller are attractive aspects of the proposed topology compared to the conventional with back-to-back converters. The control of active and reactive pow...

The Modular Multilevel Converter (MMC) represents an emerging topology with a scalable technology making high voltage and power capability possible. The MMC is built up by identical, but individually controllable sub modules. The Modular Multilevel Converter (MMC) is a new topology for multilevel converters with potential for medium voltage and high voltage applications. Equivalent Circuit mode...

A direct virtual power control algorithm is presented in this paper for VSC-HVDC startup. This control algorithm is based on direct power control (DPC) and expands the range of DPC. When the VSC converter AC side open circuit or the AC side current is zero, the control algorithm maintains the DPC feedback loop by introducing a virtual power, so that the DPC is able to control the AC output volt...
