Abstract :
This paper investigates the impact of coupling variations in an IPT lumped coil system on the overall system behaviour. An analysis of the reactive power flow between the pick-up and the primary power supply in a variable coupling system is presented. A 1.2kW battery charging system design example was conducted on how to design the resonant networks to minimize the burden on the primary power supply due to the additional reactive power demands as a result of mistuning under variable coupling condition.
