“…Due to this voltage, the stress on the parallel capacitor and inverter switches is high. By (C), (LC), and (LC) compensation topology the voltage stress on the inverter switches will reduce and current Samanta and Rathore proposed a (C) (LC) type compensation in which capacitor is connected in parallel with series (LC) at the transmitter with current-fed inversion and (LC) type compensation at the receiver side [45] as shown in Figure 7.…”

Abstract:For the past few years the feasibility of contactless power transfer (CPT) is being explored extensively as a future solution for charging electric vehicles (EVs). Studies report that the main obstacles in CPT are low power efficiency, misalignment tolerance, cost, range and charging time anxiety. This paper presents a review based on existing literature of the CPT systems for EV charging. Different cases of CPT technologies, their principle of operation and equivalent circuit based analysis is carried out. A discussion on compensation strategies and their effectiveness are reviewed and discussed. The design of coil systems for some city electric cars has been referenced in general. At the end recommendations and conclusions are made based on the study and analysis of the information available in literature.

“…With Equations (4) and (5), the power injected into the primary-side coil system, P pri , the power delivered to the load by the secondary-side coil system, P sec , and accordingly, the coil-to-coil efficiency, η cc then can be expressed as Equations (6)- (8). From Equations (6)- (8), it can be found that the input power, output power and the coil-to-coil efficiency are all closely related to the resonant frequency, the load resistance and the mutual inductance between the two coils.…”

“…From Equations (6)- (8), it can be found that the input power, output power and the coil-to-coil efficiency are all closely related to the resonant frequency, the load resistance and the mutual inductance between the two coils. In addition, the output power can be easily adjusted by tuning the DC input voltage without affecting the coil-to-coil efficiency.…”

“…From Equations (4)- (8), it can be seen that ω d has an impact on all the system operating indexes (I 1 , I 2 , P pri , P sec ); therefore, to build up a new WPT system, the first consideration is the resonant frequency. SAE J2954 recommends 85 kHz for wireless charging EV batteries [12]; ORNL's (Oak Ridge National Laboratory) experimental setup adopts 22 kHz [5], and in [13], the resonant frequency is 1 MHz, both with kilowatt-level output power.…”

Abstract:Increasing the resonant frequency of a wireless power transfer (WPT) system effectively improves the power transfer efficiency between the transmit and the receive coils but significantly limits the power transfer capacity with the same coils. Therefore, this paper proposes a coil design method for a series-series (SS) compensated WPT system which can power up the same load with the same DC input voltage & current but with increased resonant frequency. For WPT systems with higher resonant frequencies, a new method of realizing soft-switching by tuning driving frequency is proposed which does not need to change any hardware in the WPT system and can effectively reduce switching losses generated in the inverter. Eighty-five kHz, 200 kHz and 500 kHz WPT systems are built up to validate the proposed methods. Experimental results show that all these three WPT systems can deliver around 3.3 kW power to the same load (15 Ω) with 200 V input voltage and 20 A input current as expected and achieve more than 85% coil-system efficiency and 79% system overall efficiency. With the soft-switching technique, inverter efficiency can be improved from 81.91% to 98.60% in the 500 kHz WPT system.

The dynamics of a DC-AC self-oscillating LC resonant inverter with a zero current switching strategy is considered in this paper. A model that includes both the series and the parallel topologies and accounts for parasitic resistances in the energy storage components is used. It is found that only two reduced parameters are needed to unfold the bifurcation set of this extended system: one is related to the quality factor of the LC resonant tank, and the other accounts for the balance between serial and parallel losses. Through a rigorous mathematical study, a complete description of the bifurcation set is obtained and the parameter regions where the inverter can work properly is emphasized.Postprint (author's final draft
