Hi eveyone. I really need your help for this project that I will be undertaking soon. But there is much I still don't understand and my lecturers aren't around to help. The setup that I'm envisioning is like this-- Source(230V 50hz) connects to signal generator, signal generator to 1st RLC circuit and hence, magnetic induction of EMF in the 2nd RLC circuit. The 2 RLC circuits have the same resonant frequency and so they exchange power efficiently. So the questions I have are basically: 1.) What voltage should I use for the output of the signal generator? Does it depend on the ratings of the capacitors and inductors? 2.) There will always be a resistance in the LC circuits due to the resistance of the inductor. But on top of that, I need to add a separate resistor because during resonance, the reactances of the L and C cancel each other. So there would be very low impedance in the circuit , resulting in high current thus causing the power to trip. So how do i know what value of resistance to use? And is a resistor necessary for the receiving coil? 3.) Resonant frequency= 1/(2*∏*√(L*C)). So by changing my values of L and C, I will change the resonant frequencies of the RLC circuits which I am trying to tune both circuits to. Am I supposed to adjust the L and C values until I get a frequency in the ISM band? 4.) I don't understand the significance of 'Q' in power transfer. What is its implication on efficiency? Also is it true that silver plating the inductor coils can increase Q? 5.)How would I reduce the size of the receiving coil to fit into a portable device? Sorry if these questions are very basic but I would really appreciate any help. Thanks a lot.
