Seven‐level dual‐buck inverter for photovoltaic power generation

IET Renewable Power Generation
A power processing system (PPS) with a seven‐level dual‐buck inverter (SLDBI) for a photovoltaic (PV) power generation system is proposed. The PPS is comprised of a boost power converter and an SLDBI.

Artificial Intelligence-Enhanced Peak Current Mode Control for Enhanced Power Regulation in High Power High Frequency Electrosurgical Generators

IEEE Access
This study presents an AI-enhanced peak current mode controller developed for electrosurgical generators (ESG). A regression neural network (RNN) is used by the controller to minimize peak current errors. This makes the generator more accurate and stable

Two Dimensions of Financial Openness: Gross and Net Effects on Financial Development in the European Union

European Financial Management, EarlyView.
ABSTRACT We examine how financial openness (FO) affects financial development in EU countries, distinguishing its size and quality. Gross financial openness, measured by foreign assets and liabilities, reflects international integration and shows an inverted U‐shaped link with development: intermediate levels of openness enhances efficiency, but ...

Entrepreneurial Market Leadership Claims, Cultural Resonance, and Investor Evaluations in Nascent Markets: The Goldilocks Effect

Journal of Management Studies, EarlyView.
Abstract Cultural entrepreneurship research emphasizes entrepreneurs’ use of cultural resources to influence audience evaluations through resonance. However, the process by which such cultural resonance is achieved remains underexplored, particularly as an intermediary outcome.

Band‐Pass Filtering With High‐Dimensional Time Series. A Synthetic Indicator of the Medium‐to‐Long Run Component of Growth

Journal of Time Series Analysis, EarlyView.
ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

Period‐bubbling and mode‐locking instabilities in a full‐bridge DC–AC buck inverter

IET Power Electronics, 2013
In this study, the non‐linear dynamics of a full bridge DC–AC inverter controlled by fixed frequency pulse‐width modulation which is widely used in solar energy systems is investigated. The main results are illustrated with the aid of time domain simulations obtained from an accurate non‐linear time varying model of the system derived without making ...

Interrogating the Rhodes Must Fall Student Protests Through Fanonian Sociogeny: A Psychosocial Analysis of Historical Trauma and Political Violence in Postapartheid South Africa

International Journal of Applied Psychoanalytic Studies, Volume 23, Issue 1, March 2026.
ABSTRACT This article employs Frantz Fanon's sociogenic method to analyze the MustFall# student protest movement as an illustration of the psychic afterlife of colonialism in postapartheid South Africa. Fanon's sociogeny, which locates the formation of subjectivity in the reciprocal interplay between the psychic and the political, offers a framework ...

High Frequency Dual-Buck Full-Bridge Inverter Utilizing a Dual-Core MCU and Parallel Algorithm for Renewable Energy Applications [PDF]

Energies, 2017
A high frequency dual-buck full-bridge inverter for small power renewable energy applications is proposed in this paper. The implementation of the wide band gap SiC (Silicon Carbide) power device contributes to the high switching frequency of 400 kHz. This high frequency contributes to reduced converter volume as well as improved power density, which ...

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,
