Topological survey of zeta power converters from classical designs to emerging architectures

Energy Conversion and Management: X
Initially introduced as the dual single-ended primary inductor converter (SEPIC), the zeta converter has since evolved significantly from the classical direct current (DC) converter.

Fault Detection and Mitigation of DC/DC Converters with Semiconductor-Based Isolation for DC-EVSEs

In larger electric vehicle (EV) charging parks supplied by a common DC bus, the galvanically isolated DC/DC converters usually used in the charging stations constitute a significant portion of the overall costs, size and losses.

Circularly Polarized Electroluminescence and Spin‐Polarized Carrier Transport in Chiral‐Doped Polymer Films

Advanced Functional Materials, EarlyView.
Chiral dopants induce supramolecular chirality in an achiral polymer (PFO), generating spin‐polarized carriers via the chiral‐induced spin selectivity (CISS) and suggesting a possible contribution of Spin‐polarized carrier transport to circularly polarized electroluminescence (CPEL).

A new PWM Shoot-through control for voltage-fed quasi-z-source DC/DC converters

, 2017
This paper presents a new shoot-through control method applicable for an impedance source galvanically isolated DC/DC converter. In impedance source converters, the introduction of shoot-through states increases the switching speed of H-bridge switches ...

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

Advanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Time‐optimal finite control set model predictive control of non‐isolated DC–DC converters

IET Electric Power Applications
The authors propose a time‐optimal finite control‐set model predictive control (FCS‐MPC) formulation, generalised to the three most common non‐isolated DC–DC converters (buck, boost, buck–boost) tracking a constant switching frequency.

Lone‐Pair‐Induced Lattice Distortion in Lead‐Free Hybrid Perovskites for High‐Performance Nanogenerators

Advanced Functional Materials, EarlyView.
A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Modeling and analysis of CCM non-isolated high step-up interleaved buck-boost dc/dc converters

, 2012
This paper presents a new non-isolated high step-up topology by connecting two buck-boost DC/DC converters in the interleaved form. The presented topology has two identical buck-boost converters connected in a parallel-input, series-output manner for ...
