A novel dual-leg DC-DC converter for wide range DC-AC conversion

open access: yesAutomatika, 2022
This paper proposes DC–AC Dual-leg dual-stage Conversion (DDC) and DC–AC Direct single-stage conversions (DSC). Conventional energy conversion system has only two-stage conversion, so it has some drawbacks such as huge power loss, less conversion range ...

Personalizing the Pediatric Hematology/Oncology Fellowship: Adapting Training for the Next Generation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT The pediatric hematology‐oncology fellowship training curriculum has not substantially changed since its inception. The first year of training is clinically focused, and the second and third years are devoted to scholarship. However, this current structure leaves many fellows less competitive in the current job market, resulting in ...

Design of High-Efficiency Isolated Bidirectional DC/DC Converter With Single-Input Multiple-Outputs

open access: yesIEEE Access, 2019
This study mainly develops a high-efficiency isolated bidirectional DC/DC converter (HEIBDC) with a single input and multiple outputs. For the requirement of multiple output voltages with only one single input source, the proposed HEIBDC can achieve the ...
