Abstract: In medium- and high-voltage variable frequency drive systems, modular multilevel converters (MMCs) often encounter challenges related to limited switching frequency. Traditional sorting ...

Abstract: This study examines the pulsating square-wave voltage injection (SWVI) sensorless drive for interior permanent magnet synchronous motors (IPMSMs) at zero or low speed. It is well-known that ...

D-Wave is a promising pure play, but Alphabet's resources could position it to be a bigger quantum-computing winner. D-Wave Quantum has been making waves in the quantum-computing space. The company's ...

The quantum computing pure play is building an unusual architecture compared to its peers. Throughout the artificial intelligence (AI) revolution, investors have primarily turned to companies that ...

After forecasts indicated that Beijing will see citywide snowfall, the topic of "the capital city welcomes its first snow of winter 2025" is trending on Chinese social media. Netizens noted that ...

(1) This article summarizes and analyzes the implementation methods of active damping corresponding to various virtual resistor placement positions, and provides suggestions for simplifying the design ...

This raw POV session captures advanced rail surfing in its purest form — powerful carves, tight snaps, and full-wrap cutbacks with zero edits. Every turn shows the timing, speed, and precision needed ...
