Bidirectional multi‐port dc–dc converter with low voltage stress on switches and diodes

IET Power Electronics, 2020
In this study, a new transformer-less multi-port dc-dc converter with bidirectional capability is proposed. The proposed converter has dual inputs and dual outputs in which one of the inputs is considered energy storage (ES) such as a battery.

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...

Research on a three-level PFC circuit with low voltage stress

Dianzi Jishu Yingyong
Three-level and multilevel circuits have the advantages of smaller DC voltage pulsation and reduced circuit loss, and can make DC current waveform closer to sinusoidal, so a four-switch three-level PFC circuit is proposed in this paper.
