The Auto Turn off battery charger circuit shows AA batteries connected at the output end.
Can this circuit be modified to have a USB connector at the output end such that the phone can be directly connected to this circuit? Will it work in the same way if a mobile is connected at the output end? Thanks in advance. Sir I want to design a filtering circuit which will filter out put voltage generated from wind energy.

Timer IC is used here for pulse generation thus it is arranged in astable multivibrator mode. The transmitted oscillation magnetic field is detected by L-C tuned build around inductor L 2 with capacitors C 7 and C 8 which further changed to DC voltage using bridge rectifier BR 1 and filtered using capacitors C 9 and C Similarly, figure 5 and figure 6 shows solder side and component side of receiver circuit of Wireless Mobile Charger Circuit Diagram.
Figure 3: Figure 4: Figure 5: Figure 6: LC Tuned Frequency. In electronics, a choke is an inductor used to block higher-frequency alternating current AC in an electrical circuit, while passing lower-frequency or direct current DC. A choke usually consists of a coil of insulated wire often wound on a magnetic core.
So the answer is YES, you may use inductors. Moreover, what is the size of coil and the number of turns you used? Thanks for your comments. I would like to first simulate the above circuit to find the optimum value for the parameter what software do you suggest? Hi Brown, Actually this is not a complicated circuit. It is designed like this for obtaining high oscillating current. High current is necessary for increasing the magnetic fields strength.
You can get the components listed in the project through our on line shop. But the online shopping is done across India only. The receiver coil is constructed using 18 AWG copper wire having diameter of 8cm. But you should adjust the coil diameter and length for proper power transmission.
For better power transfer, the transmitter and receiver coils must be in similar size and shape also it should be tuned to the same inductance. The no of turns and diameter of the coils depends up on the inductance value. Plz go through the previous comments for detailed explanations. Hi can you please tell me how to decide the number of turns and diameter of a coil. For better power transfer, the transmitter and receiver coils must be in similar size and shape also it should be tuned to the same inductance value.
For additional tuning you need to consider about the impedance matching of the primary and secondary coils. The no of turns and diameter depends up on the inductance value. You can use this handy inductor calculator www. But it will not provide the actual reading and consider this as your start point reading. You should check out the equations given in the project.
Thank you for the Reply. Also, did you find out what is your actual power efficiency on the receiver side?
Wireless Power Transmission Mobile Charger Circuit Using Inductive Coupling
Thank you for the quick reply. Great work! We also doing this for our final course project and this is really helpful. Here in this circuit, 30 Volt is applied as the input. Then the voltage across the transmitter coil is measured as 6. When the distance between transmitter and receiver coil is 0 inches, the voltage across the receiver coil is measured as 4.
From this we get the efficiency,i. The energy transfer efficiency can be decreased by increasing the distance between the transmitter and receiver coils. So the effeciency mainly depends up on the distance between the transmitter and receiver coils. Hi, Just wondering what frequency did you use? Also did you adjust the receiver coil to tune to this frequency? It seems like that the value you used are not at the exact resonant frequency. It is desirable to tune the receiver and the transmitter coils in the same resonating frequency for better performance.
Hey, I am doing this project. I have a doubt in transmitter coil.
What do u exactly mean by the length 8. It is important to note that the transmitting and the receiving coil are similar in order to provide the best power transfer. Typically, for an inductive coupled system the two coils have the same inductance value. For this project you need to do additional tuning of the primary and secondary along with impedance matching capacitance or inductance to achieve a matched magnetic resonance. This tuning and the use of well-engineered low-loss coils in turn allow distances to be extended up to four times the diameter of the transmitter.
See all the details about such device here: Hi there, First of all, thank you for promoting my video clips.
The mobile phone wireless charging was just a demo about practical applications for the already built Royer oscillator. For a usable wireless charger in practice we need to have a different approach. There was too much wasted energy in the above project implementation, due to high frequency oscillator in use and limited access for the space needed in order to integrate the receiver into a normal mobile phone case. Good after noon Hi Shahid here. Sir I have created the same circuit in proteus labcentre software and when I run the simulation it show the error Real time simulation failed to start.
Working Principle of Wireless Mobile Charger Circuit Diagram
The coupling is further determined by the shape of the coils and the angle between them. The coupling factor is a value between 0 and 1. The value of 1 expresses perfect coupling, so all flux generated in the transmitter penetrates the receiver coil. By the other hand, a 0 value expresses a system where transmitter and receiver coils are independent of each other.
Poor coupling can be linearly compensated by a better quality factor and vice versa. Login Sign up Cart 0.
