Controlling a Switched Reluctance Motor with a Conventional Three-Phase Bridge Instead of Asymmetric H-Bridges

open access: yesEnergies, 2018
This paper proposes a new driving method for switched reluctance motors (SRMs) using the standard full-bridge inverter. In spite of changing the internal structure of an SRM, the proposed method uses an extra ring structure circuit to make it possible ...

Lumped parameter model of the novel L-C-T used in the PSFB ZVS converter

open access: yesThe Journal of Engineering, 2019
A novel inductor-capacitor-transformer (L-C-T) has been proposed to integrate the passive components into an integrated magnetic component. The phase-shift full-bridge (PSFB) zero-voltage switching (ZVS) converter with a novel L-C-T has high-power ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
