This paper describes the theoretical and experimental analysis of contactless power supply for notebook. Compensation the leakage inductances is realized through adding the resonant capacitance to the primary and secondary windings of the air gap transformer. The basic compensations topologies SS series-series and SP series-parallel are presented and compared. To consider the problem of selections resonant circuit and its parameters and achieve the maximum power delivered to the load with minimum VA rating of the power supply, the mathematical model combined the primary and secondary side is developed and the total impedance seen by the power supply converter is described. For experimental validation a laboratory set-up based on 100 W half-bridge converter with air gap coupling transformer and FPGA phase shift extreme regulator has been constructed.
