Looking back from 2026—the inaugural year of the "15th Five-Year Plan"—the EV charging industry has long since left behind the "wild west" era characterized solely by a fierce race to maximize the sheer number of installed charging piles. Accompanying this evolution is the large-scale application of...... READ MORE
IntroductionModern variable-frequency air conditioners widely employ Permanent Magnet Synchronous Motors (PMSM) to drive their compressors; the core vector control algorithms utilized in these systems impose stringent requirements on the performance of the current sampling system. Open-loop Hall-eff...... READ MORE
IntroductionAs the core component of a photovoltaic (PV) system, the performance of a PV inverter directly impacts power generation efficiency. Current sensing is critical for achieving high-efficiency Maximum Power Point Tracking (MPPT) and ensuring safety protection. While traditional shunt-based...... READ MORE
Energy—particularly non-renewable energy—has historically been a fiercely contested resource; indeed, a review of history across different eras and regions reveals that a great many wars have been waged primarily over energy. Amidst the current volatile international landscape, geopolitical tensions...... READ MORE
