A Simple Structure of Zero-Voltage Switching (ZVS) and Zero-Current Switching (ZCS) Buck Converter with Coupled Inductor

Journal of Power Electronics, 2015
In this paper, a revolutionary buck converter is proposed with soft-switching technology, which is realized by a coupled inductor. Both zero-voltage switching (ZVS) of main switch and zero-current switching (ZCS) of freewheeling diode are achieved at turn on and turn off without using any auxiliary circuits by the resonance between the parasitic ...

Highly Efficient Air Sterilization via Low‐Temperature Interfacial Evaporation in Inductively Heated Superhydrophilic Ferromagnetic Filters

Advanced Science, Volume 12, Issue 44, November 27, 2025.
The first low‐temperature interfacial evaporation air sterilization technology is presented. It is based on a superhydrophilic ferromagnetic micro/nano‐structured stainless‐steel filter, showing ultra‐efficient inductive heating. This technology has demonstrated over 99.6% of SARS‐CoV‐2 and RSV elimination at temperatures in the 60–80 °C range.

High‐Isolation and Compact Wireless Power Supply for Gate Drivers of SiC Devices With Improved Class‐E Inverter

High Voltage, Volume 10, Issue 5, Page 1282-1292, October 2025.
ABSTRACT Gate drivers for high‐voltage silicon carbide (SiC) converters require a reliable power supply with strong isolation and compact size. However, existing gate driver power supplies (GDPS) with the transformer structure make it difficult to enhance the isolation performance while keeping the small coupling capacitance and volume.

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.
