Comments on: Induction Power Transfer Circuit?

The primary and secondary circuits of a transformer are not directly connected. The transfer of energy takes place by electromagnetic coupling through a process known as mutual induction. (An added benefit is the capability to step the primary voltage either up or down.) The battery charger of a mobile phone or the transformers on the street are examples of how this principle can be used. Induction cookers and many electric toothbrushes are also powered by this technique." 2. The concept is fairly simple. Just be sure to provide a "closed loop" magnetic path (transformer core), with the "air gaps" as narrow as possible. 3. cutaway drawing of electric toothbrush induction coupling: http://electronics.howstuffworks.com/wireless-power1.htm 4. Transformer core - could use "ac clamp-on meter" ($30 at home depot); see picture: http://www.amazon.com/Fluke-Corporation-322-Clamp-Meter/dp/B00012Z0ZM/ref=sr_1_1?ie=UTF8&s=hi&qid=1279350002&sr=8-1-catcorr ------------- "The action of an electrical transformer is the simplest instance of wireless energy transfer.
