“…These values are determined for a frequency of 20000 Hz and an air gap of 150 mm without any misalignment. The LCL converter was designed to deliver an output current of 9 A through an air gap of 150 mm and with a θ of 120 o due to the inherent advantages listed in [18]. The LCL converter parameters are in Table I. In Fig.…”

This paper presents the behaviour of a full-bridge topology for an IPT system, considering misalignment impacts, and the design of a full-bridge isolated converter for an EV onboard charger fed by this IPT system. The double galvanic isolation is required since this on-board charger is expected to work also directly from the mains. The paper presents a brief description of the proposed IPT system and magnetic core structure, the strategy for the converter operation and the design of the isolating transformer. It also analyses the impact of misalignments of the IPT system on the on-board charger behaviour and control in terms of charging capability. A simulation analysis is included to verify some of the appointed considerations.Index Terms-Electric vehicles, inductive power transmission, DC-DC power converter, batteries.

“…However these control methods suffer from the disadvantage that ZVS/ZCS of the semiconductor switches is not guaranteed necessarily. For this reason another approach [6,7] is to introduce an additional DC/DC-converter to control the DC input voltage of the high frequency inverter. This has the advantage of ZCS/ZVS operation of the high frequency inverter; however additional losses in the DC/DC-converter occur and additional components are needed.…”

In inductive battery charging systems for electric vehicles the power flow to the battery has to be controlled according to the battery state of charge (SOC), the magnetic coupling between primary and secondary side and other operation parameters. It is well known that the output power can be controlled by fixed frequency or variable frequency techniques applied to the high-frequency inverter (HFI). Furthermore an additional DC/DC converter can be used to adjust the input voltage of the HFI. These three techniques are analyzed and compared by theory and laboratory measurement. It results in using an additional DC/DC converter is the best option with the best efficiency at full load. Nevertheless this technique has the highest component count and therefore the highest costs. Another technique is Asymmetric Dutycycle Control (ADC) which reaches the second best efficiency. In contrast to DC/DC converter control there is no need for additional components making this technique a good choice. Furthermore this analysis reveals that Symmetric Dutycycle Control (SDC) and Phase Shift Control (PSC) as well as Variable Frequency Control (VFC) techniques cannot compete in terms of efficiency.
