IPT has divided into three parts AC-AC converters, a magnetic coupling circuit, and AC-DC converter. AC-AC converter parts will change the system frequency to high frequency. Besides that, this converter has a current controller to make sure the current that goes to primary side not too high. The average efficiency of AC-AC converter is 85%. Also, at magnetic coupling, a study was conducted to examine the relation between misalignment coils and power transfer efficiency, between misalignment coils and coupling coefficient, as well as the relation between air gap and coupling coefficient. A 3D modeling is done using Finite Element Method (FEM) with JMAG. At the 50-kHz resonant frequency, the results show that the power transfer efficiency decreased significantly when the misalignment between the two coils reached 160 mm or more, between misalignment with efficiency has a negative correlation, the relation between the misalignment with coupling coefficient has negative correlation, and the relation between the air gap with coupling coefficient also has negative correlation. And the last part is the AC-DC converter circuit with charging regulator used. The AC-DC converter consists of a series of rectifiers, buck converters, and controls used in battery charging. The simulations were performed to study the battery charging scheme as well as the value of the parameters designed using PSIM and Matlab Simulink software to the voltage change and the state of charge (SOC) of the battery.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Ac-dc converters,Current controller,Inductive power transfer,JMAG,Resonance frequencies[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]a current controller,high-frequency AC-AC and AC-DC converter,Inductive Power Transfer,JMAG,resonance frequency[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICEVT.2018.8628380[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
