Abstract

In Dynamics Inductive Power Transfer (DIPT) applications, power pad is the main mechanism to transfer the power through air-gap. The power pad consists of multi- transmitters and a receiver that linked together by magnetic flux. In practice, position and number of transmitters on the ground affect the amount of energy pick-up that should be considered. This paper presents a study of the relationship between energy pick-up versus transmitters spacing and vehicle velocity in DIPT application. The spacing between the transmitters and vehicle velocity was optimized for the defined energy pick-up from a proposed mathematical model. The LCC-S topology and secondary auxiliary coil were adopted in the proposed system because the system can provide a constant magnetic coupling condition along with the distance. The proposed system was designed according to SAE J2954 WPT1/Z2 Standard. The feasibility of the proposed method was confirmed by COMSOL multiphysics (FEA) and LTspice simulations.
