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...

This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...

This paper proposes a new solar power generation system, which is composed of a DC/DC power converter and a new seven-level inverter. The DC/DC power converter integrates a DC-DC boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor se...

The migration metallic species between Al2O3 and CeO2-ZrO2 (CZ) is one of the main causes for deactiviation three-way catalysts (TWCs). In order to address this issue, κappa-phase κ-Ce2Zr2O8 was constructed strengthen Pd-CZ interaction thus stabilize palladium species. For comparison, tetragonal-phase Ce0.5Zr0.5O2 with phase (κCZ) without (tCZ) were prepared. (κCZ+Al2O3) supported catalyst (Pd/...

A novel integrated buck-flyback non isolated power factor (PF) correction (PFC) converter is proposed in this paper. This new converter is an inherent integration of a buck converter and a flyback converter, which operates in either flyback mode or buck mode according to whether the input voltage is lower or higher than the output voltage. In this way, the dead zones of ac input current in trad...

Fluidized-bed Catalytic Cracking (FCC) is a process subject to frequent variations in the operating conditions (including feed quality and feed rate). The production objectives usually are the maximization of LPG and gasoline production. This fact makes the FCC converter unit an excellent opportunity for real-time optimization. The present work aims to apply a dynamic optimization in an industr...

This paper presents the three topologies of three-phase four-wire DSTATCOM for reduction of harmonics, reactive power compensation, increasing power factor, which occur due to a nonlinear load, environment problem and polluted grid. The performances of the above topologies have been compared for the magnitude of source current, power factor improvement, DC-link voltage regulation, and total har...
