Web4 Dec 2016 · The magnitude of brush losses depends on the voltage drop at the contact point and on the armature current. Note that brush losses are sometimes included in the category of stray load losses. Stray load losses Losses that cannot be easily accounted for are generally lumped into the “stray load” category. http://www.rakov.ece.ufl.edu/teaching/3211/Packet/5_Synchronous.pdf
WebA switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently..
