Data‐Driven Temperature Deviation Estimation of a Proton Exchange Membrane Water Electrolyzer Stack from Electrochemical Impedance Using Machine Learning

IEEJ Transactions on Electrical and Electronic Engineering, Volume 20, Issue 9, Page 1488-1496, September 2025.
We developed a method to analyze temperature variations in proton exchange membrane water electrolysis stacks by using machine learning to interpret electrochemical impedance spectroscopy (EIS) data. To train the machine learning model, we artificially generated impedance data at various temperature differences by merging data from uniformly heated ...

A New Soft‐Switched Trans‐Inverse Step‐Up DC/DC Converter With Zero Input Current Ripple

Energy Science &Engineering, Volume 13, Issue 2, Page 714-727, February 2025.
ABSTRACT In this article, a new single‐switch high step‐up DC/DC converter with soft‐switching performance is presented for sustainable energy applications. In this circuit, zero input current ripple is obtained at a small value of the input inductance. Therefore, the ohmic loss of the input inductor will be significantly alleviated.
