Hi, Im new to this forum.
I am making an enquiry on behalf of a freind. he like me has very little time, resources and knowledge.
He seems to think that if he were to wire the primary of a transformer in an H bridge pattern of transistors thereby being able to square wave pulse the primary alternately.
(ie one pulse goes in one end and the next pulse goes in the opposite end and so on, possibly at resonant frequency or not? ,50 % duty cycle), that the inputted pulse would always be travelling in the same direction or in harmony with the inducted current in the primary from the magnet flux generated by the secondary,,, and the magnetic flux generated by the input pulse would reinforce the already existing flux generated by the secondary. Pulsed this way , he thinks that the core of the transformer could be driven into saturation with a lot less power. Then harvesting the back emf of the primary(bedini styles great idea) to charge a battery and recifying the secondarys he would have COP>1.
I think that it is a silly idea and that he should pursue some of the more practicle ideas but he wont listen to me. but I could be wrong.
If I were to show him the reasoning of more experiened people who have a deeper understanding of the interplay that goes on in transformers with respect to flux paths, induction, reinduction of primarys from secondarys,
lenzes law ect, to explain to him why hes wasting his time, we could put this matter to rest and move on.
Any input regarding the above would be appreciated.
Regards Lotec
