MatWPT is an innovative software to support designers during the analysis and development of Wireless Power Transfer (WPT) systems. The software, developed as a Matlab toolbox, receives the key system characteristics as inputs, such as compensation topology, operating frequency and desired output power. Then, using evolutionary optimization, provides potential design options for meeting the performance criteria defined by the designer, in terms of output power and efficiency.

Accurately detecting power line defects under diverse weather conditions is crucial for ensuring power grid reliability and safety. Existing power line inspection datasets, while valuable, often lack the diversity needed for training robust machine learning models, particularly for adverse weather scenarios like fog, rain, and nighttime conditions. This paper addresses this limitation by introducing a novel framework for generating synthetic power line images under diverse weather conditions, thereby enhancing the diversity and robustness of power line inspection systems.

Different countries have various grid voltages, and different electric vehicles (EVs) have different chassis heights. Conventional EV wireless power transfer (WPT) solutions require designing different circuits for various input voltages and using different compensation circuits for different transmission distance classes which hinders the widespread adoption of the WPT technique. To address these two issues, this paper proposes an EV WPT system based on series-parallel inverters. The mathematical model of this system is established, and the expression for output power is derived.

The pulse parameter-editable nanosecond pulse power supply (NPPS) based on all-solid-state Marx power topology is one of the critical excitation sources for studying the characteristics of atmospheric pressure low-temperature plasma (APLTP), its efficient applications, and the regulation of discharge characteristic. We have developed a 20kV/400W nanosecond pulse power supply with editable pulse edge parameters to validate the effectiveness of the diode-capacitor network (DCN) method.
