In order to study the saturation characteristics of electric locomotive transformer, the flux-current model of electric locomotive transformer is firstly established, and then the flux-circuit model ...

A research team led by Dr. Shen Jinhua from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences has investigated rapid spatiotemporal vertical electric currents (VECs) ...

Employing synchronous optimal pulsewidth modulation (PWM) techniques permits operating the PWM inverter of medium-voltage drives at very low switching frequency. The switching losses of the power ...
