“…A capacitance calculation method is proposed in [12]. Unlike the method presented in II.C, it is an interesting way to compensate the reactive part of the transformer by solving (9) to (12), and therefore finding the compensation capacitances independently from the transformer's parameters. This methodology is mostly relevant for cases where the design of the primary part (inverter) and the one of the secondary part (battery charger) are not provided by the same developers.…”

In this paper, the case of a battery charger for electric vehicles based on a wireless power transmission is addressed. The specificity of every stage of the overall system is presented. Based on calculated and measured results, relevant capacitive compensations of the transformer and models are suggested and discussed in order to best match the operating mode and aiming at simplifying as much as possible the control and the electronics of the charger.

“…The following example, extracted from [12], shows the robustness of the method: The WPT is first tuned using the EOC and then the COC methods, while having a medium load (R L = 30 Ω). For both cases, the load is then increased to a higher load (R L = 4 Ω).…”

“…In their study [8], the authors emphasized the need for effective misalignment tolerance strategies to overcome the observed reduction in power transfer efficiency to 70% at 15 cm lateral displacement. Studies on the role of compensation networks are reported in [2,[12][13][14], in which the different topologies are compared in terms of their dependencies on coupling and loading conditions and their impacts on the resonance frequency. In particular, the authors in [13] compared the performance of different compensation topologies in terms of output voltage regulation and efficiency stabilization at different coupling conditions, i.e., different misalignments.…”

Dynamic wireless power transfer (DWPT) systems are becoming increasingly important for on-the-move electric vehicle (EV) charging solutions, to overcome range anxiety and compensate for the consumed energy while the EV is in motion. In this work, a DWPT EV charging system is proposed to be implemented on a straight road stretch such that it provides the moving EV with energy at a rate of 308 Wh/km. This rate is expected to compensate for the vehicle’s average energy consumption and allow for additional energy storage in the EV battery. The proposed charging system operates at an average power transfer efficiency that is higher than 90% and provides good lateral misalignment tolerance up to ±200 mm. Details of the proposed system’s design are presented in this paper, including EV specifications, inductive link and compensation network design and power electronic circuitry.

“…The load characteristic is a very important point since it determines the output voltage and current when the load value changes. It has been calculated in [9]. As a first step, the electric equivalent circuit of the transformer and its four well-known compensation topologies are introduced.…”

Contactless power transfer using inductive coupling is a well-known way to transfer energy from a transmitter to a receiver without any physical link. The applications are multiple. In this paper, the design and control of such a system for a contactless battery charger is investigated. The behaviour of the battery turns the system into a non-linear one. A solution dealing with the compensation topologies which aims to simplify the control of the transformer without any additional power electronics is proposed.
