“…This configuration of power electronic system (Figure 19 orange blocks) is providing low ripple input current with sinusoidal character, low THDi, excellent power factor and controllable output voltage. Therefore, it is not required to implement another dc/dc converter stage within the system [29][30][31].…”

The paper introduces the main issues concerned with the conceptual design process of wireless power systems. It analyses the electromagnetic design of the inductive magnetic coupler and proposes the key formulas to optimize its electrical parameters for a particular load. For this purpose, a very detailed analysis is given focusing on the mathematical concept procedure for determination of the key factors influencing proper coupling coils design. It also suggests basic topologies for conceptual design of power electronics and discusses its proper connection to the grid. The proposed design strategy is verified by experimental laboratory measurement including analyses of leakage magnetic field.

“…The recent developments in standards (STD) such as SAE J2954/1 [1], IEC 61980-1:2015 [2], and ISO 19363:2020 [3] are prime examples of recognizing this technology among the industrial partners. An IPT system consists of input-side and output-side power electronics converters to control and transfer the power through the coupler, depending on the load dynamics [4], [5]. The coupler should operate efficiently while minimizing the leakage magnetic fields to ensure living beings' safety [5]- [9].…”

The coupler parameters, such as transmitter inductance (L Tx ), receiver inductance (L Rx ), and the coupling coefficient (k) or mutual inductance (M), vary with the misalignments. Their variations must be quantified and incorporated into the design and optimization stage as they impact performance indices such as efficiency and leakage magnetic field. Most of the solutions proposed in the literature compromise the performance of the coupler in search of a misalignment-tolerant design. Therefore, this paper presents a method to incorporate the misalignments into the design and optimization process of an IPT coupler by utilizing robust optimization, where misalignments are considered as noises/disturbances/uncertainties to a perfectly aligned coupler. The optimized designs resulting from this method will not compromise the performance of the coupler in search of a misalignment-tolerant design. The effectiveness of the proposed robust optimization method is experimentally verified with a 3.7 kW hardware prototype.
