Abstract :
When an inductive power transfer system is applied to a battery charger for electric vehicles, a diode bridge rectifier with a dc-dc converter, called a secondary-side converter in this paper, is connected to the secondary side of the resonant circuit in order to regulate the current and voltage of battery. At that time, a type of the secondary side converter and an input voltage of the primary-side inverter affect the efficiency of the whole system. Therefore, this paper investigates the influence of secondary-side converter and the primary-side inverter input voltage on the total efficiency of the system by experiments and theoretical analysis.
