Design and Analysis of a New High Step-Up Converter Using Switched-Inductor-Capacitor Voltage Multiplier Cells for Photovoltaic Application

IEEE Journal of the Electron Devices Society
This article proposes a new high-gain converter to attain higher output voltage without coupled inductors. The operation of the proposed converter is examined under continuous conduction mode (CCM) and discontinuous conduction mode (DCM).

A Stress-Relaxed Negative Voltage-Level Converter

IEEE Transactions on Circuits and Systems II: Express Briefs, 2007
In this brief, a new embedded negative voltage-level converter (level shifter) is presented. The proposed circuit can convert a positive input signal to a negative output signal with reduced or even without (depending on the application) voltage stress on the used MOS devices.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Modified A-Source Converter Operating at Lower Voltage Stress [PDF]

IEEE Access, 2019
The coupled inductor based Z-source converter produces higher voltage gain with lower number of components count. In this paper, a new two winding mutually coupled inductor based Z-source DC-DC converter is proposed to boost the voltage gain. The proposed converter utilizes reduced number of passive elements count to produce higher voltage gain ...
