Resources and Going Further

One of the ways you can take this project further is increase the efficiency of the wireless power transfer. If you have access to an LCR meter, which can measure inductance, capacitance, as well as resistance, you can find the exact values of L1 and C1 of the secondary windings and feed the values into a LC resonance calculator. Once you know the resonant frequency of the secondary, you can measure the inductance of the primary coil and have the calculator return the capacitance value. Adding that capacitor in parallel with the primary inductor and adjusting the signal generator to that frequency should increase the efficiency. But for now, checkout some the links below:
