For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...
Introduction Virtual reality-based telerehabilitation (VR-TR) combines gamified exercises with remote supervision for people with Parkinson’s disease (PD). Its effectiveness and safety in PD remain ...
Recent patent disclosures indicate that BYD has strengthened its work on variable-flux permanent-magnet synchronous motor technology, with four filings published by the China National Intellectual ...
Abstract: The existing double-vector (DV) model-predictive control for a permanent magnet synchronous motor (PMSM) selects the optimal voltage vector (OVV) combination by traversing 12 alternative ...
Abstract: To address the issues of slow convergence, significant chattering, and poor suppression of high-frequency interference in sliding mode observer(SMO) for sensorless control of permanent ...
Frequency Electronics’ Q1 was weaker than expected due to early-July budget finalization and customer delays. Still, management reported no contract cancellations and suggests that subsequent quarters ...
What if a single innovation could save industries millions of dollars, slash carbon emissions, and redefine what we thought was possible in energy efficiency? Enter ABB’s new 56.2 MW brushless ...
ISA automation professionals explain key considerations for using variable frequency drives. Variable frequency drives (VFDs) are widely used in industrial fan, pump and air compressor applications, ...
It begins as random flashes of greenish-yellow light in the night. And then, slowly, something incredible unfolds. A rhythm of pulsating light illuminates Great Smoky Mountains National Park. The ...
Black screens, silent radios and near misses: Air traffic control outages are not isolated to Newark
Years before recent communications blackouts led to widespread chaos at Newark Liberty International Airport, air traffic controllers and pilots around the country repeatedly reported equipment ...
Synchronous fireflies are returning to the Great Smoky Mountains National Park for their annual light show, and now we know when. The National Park Service announced the peak dates for viewing the ...
