ORIGINAL RESEARCH

Study of the decoupling magnetic integrated high‐frequency transformer for DC/DC converter
Dezhi Chen, Shichong Zhang, Baodong Bai, Zhixiang Zhang, Zhaoning Yang

Version of Record online: 27 November 2023

Description unavailable

In order to reduce the number of discrete transformers and increase the power density as well as the reliability of the power converter, a three-port isolated DC/DC converter with a decoupling magnetic integrated high-frequency transformer (DMIHFT) is proposed for the DC microgrid in this paper. Three discrete transformers are integrated into a single common core, and magnetic decoupling is achieved among each transformer by rational design at the same time.

ORIGINAL RESEARCH

High voltage gain switched z‐source inverter with low current stress
Golaleh Zarei, Ebrahim Babaei, Mohammad Bagher Bannae Sharifian, Hadi Aghaei, Elias Shokati Asl

Version of Record online: 27 November 2023

Description unavailable

This paper proposes a switched Z-source inverter with high voltage gain and low current stress on elements. Also, a new switching method corresponding to the proposed topology is introduced. This method is based on the usual Maximum Constant Boost (MCB) method. Eliminating part of the inverter's switching in this modulation method improves the inverter's efficiency. In addition to the Shoot-Through (ST) duty cycle, another variable (N) affects the inverter's boost factor in this switching method. The proposed inverter's dynamic analysis shows that introducing N in the modulation method improved the dynamic characteristic of the inverter. For the proposed topology, steady-state analysis, dynamic analysis, elements design and efficiency calculation are performed.

REVIEWS

A critical review on contemporary power electronics interface topologies to vehicle‐to‐grid technology: Prospects, challenges, and directions
Moshammed Nishat Tasnim, Jannatul Mahi Khan Riana, Tamanna Shams, Mohammad Shahjalal, Nafis Subhani, Md Rishad Ahmed, Atif Iqbal

Version of Record online: 27 November 2023

Description unavailable

Integration of electric vehicles (EVs) with the smart grid system is a potential solution to deal with a large number of EVs. The emerging bidirectional converter topologies to interface EVs and the analysis of promising charging or discharging structures are discussed. Scopes of vehicle-to-grid (V2G) framework and prime barriers in achieving the significant benefits from V2G technology are identified
