Modelling and performance evaluation of diode‐assisted impedance source networks
IET Power Electronics, 2021 This paper deals with a family of two‐ and three‐windings coupled inductor‐based impedance source networks. They have been basically derived from the successful quasi‐Y‐source network (q‐YSN) by replacing one of its capacitors with a diode with different

Chemically Fueled Systems Chemistry Across Length Scales
Advanced Functional Materials, EarlyView.Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Improving Circuit and Transformer Complexity for 24-Pulse AC-DC Converter Topology
IEEE AccessThis paper proposes a novel three-phase 24-pulse diode converter topology derived from cascading two 12-pulse rectifiers. Unlike existing designs that use multi-tap Interphase Reactors (IPR) or transformers, our configuration eliminates the need for ...
