Abstract: The influence of the pulse width modulation (PWM) excitation on the DC winding induced voltage pulsation for the wound field switched flux (WFSF) machine is investigated in this paper.

Three California-based scientists have been awarded the Nobel prize in physics for their observations of quantum mechanical tunnelling on the macroscopic scale. The discovery by John Clarke, Michel ...
