AI Thread Summary
To maximize wireless charger efficiency, focus on optimizing coil design and switching rates, ensuring strong coupled resonance by selecting the appropriate frequency. Experimenting with different coil configurations and inductance values is crucial for improving power transfer from the transmitter (Tx) to the receiver (Rx). Understanding the type of power supply needed, whether AC or DC, is essential for effective operation. Further research and experimentation are recommended to enhance knowledge and skills in wireless charging technology. Engaging with online resources may provide additional insights and guidance for the project.

hi... now I am in progress to do a wireless charger pad by using coil. so I've seen a lot of project regarding to this wireless charging. do u have any idea how can i make it more efficiency? meaning that how can i get a maximum power transfer while transferring the power from Tx to Rx. normally i see all the project only can achieve until 57% from the actual charger by using all those clumsiness wires charger... hope u can give me any suggestion or idea .thanks. :smile:

Do a load of experiments with coils and switching rates. You need to figure out what frequency you are going to operate at, learn how to obtain/wind a coil of the inductance that you want to get strong coupled resonance, and then figure out how to build an efficient power circuit to drive your Tx coil.

can u explain what do you mean by choosing the frequency? actually i have watch a lot of videos about the wireless charging by using inductive coil and one thing that I am not clear is what kind of power supply that we need to use? either AC or DC? :confused:

I really don't want to sound unhelpful, but you are too far down the learning curve this time around for this project. I suggest you put your time into shopping on the internet for what you are after.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
