INDUCTIVE POWER TRANSFER TECHNOLOGY FOR MOBILE BATTERY CHARGER
A Thesis presented in partial fulfillment of the exigency for the degree of Bachelor of Technology in “Electrical Engineering”

Under guidance of Prof. SUSOVAN SAMANTA
Inductive power transfer (IPT) is an application of electromagnetic induction principle. Since electromagnetic induction phenomena is directly proportional to the operating frequency, so as we increase the operating frequency, amount of energy transfer from one coil to another coil will also increase. As our power supply frequency is 50Hz so at this frequency, amount of energy transfer from one coil to another coil will be very less. In this thesis it is shown that, to transfer maximum amount of energy from one coil to another coil, it is necessary to use IPT at high frequency. At high frequency skin effect is more pronounced but there is a resonant frequency where overall efficiency is more in spite skin effect. To increase the power factor of IPT circuit compensated capacitor has used. There are four types of compensated topology but to use the IPT circuit in mobile battery charger primary-series-secondary-parallel (P-S-S-P) is more useful.
