Wireless power transfer has been introduced as a proper replacement for conventional cable power transfer systems recently. With the developments of the electric transportation, transferring power wirelessly has been found to introduce several advantages in charging Lithium-Ion batteries. Among different configurations of wireless power transfer, Series Parallel structure is found to be more interesting...
This paper deals with attractive voltage-source single-ended sub-resonant high-frequency (HF) inverter as a simple wireless power transfer (WPT) based on unidirectional inductive power transfer (IPT) in addition to bidirectional HF converter as transmitter and receiver of WPT is developed for vehicle to home (V2H) smart energy management architecture. Firstly, the voltage source single-ended sub-resonant...
This paper deals with a cost effective IPT wireless EV battery charger which incorporates the simplest quasi-resonant soft switching pulse modulated inverter. In the first place, the operating principle of the single-ended high-frequency resonant inverter linked IPT DC-DC converter treated here is described. This two planar coupling coils type wireless resonant DC-DC converter can efficiently operate...
This paper discusses the characteristics of a series-series compensated inductive power transfer system (IPT) with theoretical analysis and experimental results. To maximize system efficiency, two-stage structure, which includes a PFC stage and a resonant DC-DC stage operating in ZVS region, is proposed. One of the major design challenges in implementation of a practical contactless EV charger is...
This paper presents a primary side control method for a low power wireless energy transmission system (WETS), with no physical wire connection required between the primary and secondary-side circuits. The primary side control method implemented in the WETS does not require extra space in the secondary side to regulate transmission energy. A charging protection was embedded within the secondary side...
