AC vs DC

We all know Thomas Edison, his accomplishments are legendary, over 1000 patents were issued to this prolific inventor. Nikola Tesla, noted Serbian academic, was another inventor from the same period, trained in Europe as an engineer, he emigrated to the United States where he never attained the stature of Edison but arguably accomplished more. He is the inventor of our modern electrical power grid. This video summarizes this accomplishment and the role that both Edison and Tesla played in this accomplishment.

 

Voltage doublers

From the United States Department of Defense.  Explains the theory of operation of a voltage doubler.  Traces charge an discharge paths for the capacitors.  Determines peak output voltage and ripple frequency.
