efficiency analysis systems [11]. and optimal of IPT with genetic algorithms (GA) were However, the operating frequency effect is not presented. Before the GA optimization process, the IPT considered. The reference [12] designs the IPT system by system was compensated in a resonance condition to using an optimization algorithm. But the algorithm minimize the VA rating of the power supply and achieve maximum power transfer. In the process of GA ignores the effect of coupling coefficient. Reference [13] optimization, to ensure the final solutions achieving analyzed all the parameters that influence the efficiency bifurcation-free operation, the solutions that generate and presented an optimal algorithms design method, bifurcation phenomenon (multi zero phase angle frequency) however, the algorithms cannot ensure to find out the was excluded. The simulation results verify that the GA can most optimal solution and the bifurcation phenomenon find the best optimal solutions for all topology IPT systems. ignored. In this paper, the GA is selected to efficiency optimal Index Terms—IPT System, Efficiency Optimal, Genetic design of the IPT system undertakes the resonance Algorithms conditions. In the process of the GA optimization, the solutions that generate bifurcation phenomenon are I. INTRODUCTION excluded. The simulation verifies that the GA can find Inductive power Transfer (IPT) has been used in many the best optimal solutions for all base topology IPT commercial and industrial applications due to its ability systems. to transfer electrical power without and physical contact [1-2]. The IPT system includes two independent mutually II. EFFICIENCY ANALYSES OF BASE IPT SYSTEMS coupled part called primary and secondary respectively With different compensation, there are four basic [4]. The primary part generates an essentially current ip topology IPT systems that called SS, SP, PP, and PS are in the primary coil L with a resonant high frequency p shown in Fig.2, where the first S or P stands for series or switching power supply. The primary compensation is parallel LC compensation of primary resonance and the used to minimize the VA rating of the supply. On the second S or P stands for series or parallel LC secondary part, compensation is also required to enhance compensation of secondary resonance. The inductor L the power transfer. A switched mode controller is p and Ls represent the primary and secondary coil normally used to control the power flow from the respectively. The resistance R represents the load on the secondary coil Ls to the load. secondary, while the resistance R and Rs represent the Because of large air gaps via magnetic coupling, the p self resistance of L and Ls respectively. efficiency is a signification target that must be considered p The voltage Vin is the output voltage of the converter. when design of the IPT systems [6,7].
