Q: Is it possible to increase the transmitting range?
A: Yes, it is possible to increase the transmitting range.
Q: What is wireless power transfer?
A: Wireless power transfer is transferring of power wirelessly, using mutual induction of 2 coils in HF.
Q: What is the concept used in this project?
A: The project follows the concept of using inverters with high frequency transformers to generate AC signal of higher frequency.
Q: Can a lamp be used as a load?
A: Yes, a lamp can be used as a load.
Q: Can I use LEDs instead of fan motor as the load?
A: Yes, a maximum of 100 white LEDs can be used.
Q: Can the power be transferred wirelessly, even if I place a object in between?
A: Yes, power can still be transferred.
Q: Are the formulae used in the project available in the documents?
A: Based on Resonant frequency, calculating the capacitor value on measured coil inductance is available in the documentation provided with the project.
Q: Is it possible to add both devices together such as bulb and fan?
A: A small LED load and a fan can work together.
Q: How to achieve the resonant power transfer between the two coils & to have them at resonance?
A: F=1/2Pi*sqrt (L*C)-(http://www.1728.org/resfreq.htm) Example At F=40 KHz , For resonance -C=0.13uF is in series with the coil of about 117 uH.
