Abstract :
A practical dynamic inductor-tuning circuit for a parallel resonant ICPT power pickup operating at 38.4 kHz is described. The method controls the current through a tuning inductor by varying the turn on delay of two power switches. This varies the inductor current so that the tank may be maintained at resonance. Supporting mathematical analysis, circuit simulation and prototype measurements are included. Experimental results have verified the system behaviour
