I'm an ee student and for the group project we have chosen to make a Wireless power transfer. Our goal is to charge a laptop. As for the result we have to demonstrate charging a laptop, so considering modern laptops I think we need at least 60-80 watts of power to be transferred to the receiving coil.
So for the first step we need to create the driver for the primary coil which will creates an alternating current using DC voltage, for the purpose we intend to use a H-bridge and a mosfet driver and an arduino. The purpose of using an arduino is to be able to vary the switching frequency. Also we intend to use resonant mode instead of inductive mode because the resonant mode can transfer energy more than inductive.
As our syllabus doesn't cover any of this wireless power transfer, we are gathering information and learning of it.
Is the use of h-bridge is suitable for this purpose? Input voltage of transferring is 12volts, on which factors we should choose the mosfets on the current rating.
We are also in a tight situation as we only have about 2 months to complete this.
Note:- the distance between two coils can be just few centimetres and the receiving coil won't be built to the laptop. For the demonstration purpose we will just use the secondary coil and laptop apart from each other.
Any help would be appreciated. Regards
