“…The control variables are now the primary phase shift, φ' S , and the secondary phase shift, φ S . For the phase-modulated waveform of V 1 , whose amplitude is V dc and whose dutycycle is linked to φ' S , the following expression occurs: (17) In order to obtain a 24 V amplitude waveform for V 1 , same as the one displayed in Fig. 3, V dc in this primary full-bridge configuration must be the half of V dc in the half-bridge configuration, so that, in the following power equations, obtained by replacing (17) in (10) and (15), and considering a 90° phase delay φ D , V dc is 24 V:…”

Wireless charging techniques, based on Inductive Power Transfer (IPT), are attractive for Electric Vehicles (EV), due to benefits such as convenience and safety. An accurate valuation of the maximum achievable efficiency in an IPT system is extremely unlikely due to the high sensitivity to parasitic elements variations. Therefore, an �on site� procedure of power efficiency characterization is useful to get a precise description of the efficiency curve and obtain the actual maximum efficiency. In this paper, a power tracking algorithm aiming at efficiency maximization is proposed for a Wireless Charging system. The algorithm aims at finding the maximum power transfer efficiency with respect to two control variables

“…By properly driving this stage, it is possible to regulate amount and direction of the power flow. IPT systems with power regulation based on an active rectifier are well-reported in literature [16][17][18]. The power control is based on the regulation of some variables, like the "phase delay" and the "phase shift".…”

This paper presents an automotive suitable power electronics for inductive energy transfer of up to 22kW within a box volume of 3.5l. The compact layout and an optimized system topology allow the realization of rectifier and reactive current compensation with a high efficiency of around 98%. The specific layout takes into account cooling of the resonance capacitors as well as of the rectifier. The automotive environment requires failsafe functionality which is independent of the wireless data transfer to the primary side. The hardware is dimensioned and prepared for realizing an additional secondary side power control. Thus, the optimal electrical working point of the energy transfer can be adjusted and overall system losses can be reduced.

Inductive Power Transfer (IPT) allows to wirelessly supply electronic devices. Thus, it is a very smart technique of battery charging for electric vehicles. In a parking area scenario, IPT is a proper method aiming at the energy transfer from the vehicle battery to the electric grid too. Bi-Directional Inductive Power Transfer (BDIPT) Systems are an attractive solution for the automotive market. Due to the great relevance of the energy saving problem, the goal of an efficiency maximization is researched by the energy market. In this paper, an in-depth investigation of the power efficiency in BDIPT systems is carried out, aiming at the optimum efficiency
