The Infeasibility of a Zero-Current Switching Class E Amplifier

, 1990
It has been shown that a class E amplifier may be configured to provide nearly 100-percent efficiency and zero-current or zero-voltage switching. A particular configuration, which supplies zero-current-switching when the transistor output capacitance is ...

Role of induced exchange bias in zero field spin–orbit torque magnetization switching in Pt/[Ni/Co]/PtMn

AIP Advances, 2020
Current induced magnetization switching is of particular interest to develop non-volatile magnetic memories (MRAM). We studied spin–orbit torque (SOT) switching in a Pt/ferromagnet/antiferromagnet Pt/[Co/Ni]2/PtMn Hall cross. For the as-deposited sample,

Steady-State Analysis Of Full-Bridge Zero-Current Switching Converter

, 2000
A steady-state analysis of the full-bridge zero-current-switched (FB-ZCS) pulsewidth modulation (PWM) converter is presented. The FB-ZCS is fully able to incorporate parasitic parameters, and zero-current turn-off characteristics.

Soft-switching single inductor current-fed push-pull converter for PV applications

, 2014
A switching control strategy is proposed for single inductor current-fed push-pull converter with a secondary side active voltage doubler rectifier or a voltage rectifier used in photovoltaic (PV) grid interfacing. The proposed switching control strategy

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

A New SEPIC-Flyback DC-DC Converter for Fuel Cell Systems [PDF]

Hydrogen, Fuel Cell & Energy Storage
In this study, a SEPIC converter featuring a novel lossless snubber circuit is proposed for fuel cell applications. In the proposed topology, the main switch turns on under Zero-Current Switching (ZCS) conditions and turns off under Zero-Voltage ...

Abatacept for Prophylaxis of Acute and Chronic Graft‐Versus‐Host‐Disease in Children Undergoing Allogeneic Hematopoietic Stem Cell Transplantation—A Systematic Review and Meta‐Analysis of Cohort Studies

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.
