State feedback linearized model for phase-controlled series-parallel resonant converters [PDF]
This paper proposes a linearized large-signal state space model for phase-controlled series-parallel resonant converter. The model combines multiple-frequency and average state-space modeling techniques to generate a universal model with DC state ...

Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS
ABSTRACT Introduction Cognitive impairment is common in multiple sclerosis (MS), but manifestations following the first demyelinating event are relatively unexplored. We investigated cross‐sectional associations between magnetic resonance imaging (MRI)–derived brain volumes and the presence of cognitive impairment outcomes five years after the first ...

Regenerative braking using buckboost converter [PDF]
A Buck Boost converter circuit has been designed and simulated to drive a dc motor for an electric vehicle. The design consists of an IGBT Buck-Boost converter, the battery pack in the Buck side and a capacitor in the Boost side. The main battery has the

Distributed control of a fault tolerant modular multilevel inverter for direct-drive wind turbine grid interfacing [PDF]
Modular generator and converter topologies are being pursued for large offshore wind turbines to achieve fault tolerance and high reliability. A centralized controller presents a single critical point of failure which has prevented a truly modular and ...

A non‐isolated single‐input dual‐output boost DC–DC converter
A new non‐isolated single‐input dual‐output boost DC–DC converter is introduced in this paper. The motivation of the work is that in various applications such as some multilevel converters, it is required to provide multiple dc sources that are not ...
