Abstract Due to the influence of material characteristics and winding power, single output electromagnet has limited ability to improve the dynamic characteristic of electro-hydraulic valve. Therefore, an electromechanic...

Introduction. Nowadays, the most widely used wind energy conversion system in wind farms is based on a doubly fed induction generator (DFIG); it has a large speed range and can function in multiple modes. Problem. Harmon...

Background In multiple sclerosis (MS), delays in initiation of disease-modifying therapy (DMT) are associated with worse clinical outcomes. Methods This single-center retrospective chart review study included treatment-n...

ABSTRACT Background Multiple sclerosis (MS) is the most prevalent immune‐mediated neurodegenerative disease affecting the central nervous system. Ocrelizumab, a humanized anti‐CD20 monoclonal antibody, has demonstrat...

This article presents the design and simulation-based evaluation of a 225 kW grid-interactive bidirectional fast DC charger for electric vehicles operating in both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) modes. T...

The output voltage of PWM power inverters shows harmonic distortion due to several causes; the main ones are the modulation algorithm, nonlinearities in the output filter, dead times, voltage drops across the switches an...

Abstract Multi-level inverters (MLIs) are also used in relatively high-power systems; but the goals of low overall harmonic distortion (THD) and fewer power semiconductor devices remain a design issue of serious difficul...
