“…Additionally, the development of more efficient and compact LLC resonant converters could pave the way for new applications and innovations in the field of wireless power transfer. Although various converters have been proposed for inductive coupling WPT (ICWPT) applications [16,[19][20][21], the LLC resonant converter stands out for its simplicity and efficiency [ 16 ] , This approach utilizes an air-core transformer instead of a conventional iron-core transformer, thereby reducing costs. The control of the LLC resonant converter in ICWPT applications can be achieved through pulse frequency modulation (PFM).…”

The LLC resonant converter is a widely utilized power electronics converter, due to its numerous industrial and domestic applications. This converter offers some advantages such as soft-switching operation of all switches, high efficiency, high power density, low voltage stress, minimal electromagnetic interference (EMI) noise, input/output isolation, wide input/output voltage range, and reliable and good performance under the wide load variation ranges, as well as good light-load operation. However, this converter has certain limitations, which can be addressed to enhance its operation and efficiency. This paper provides an in-depth review and comparison of various LLC-based resonant converter configurations, focusing on their operational principles, mathematical analysis, control methods, and some practical applications including electric vehicle chargers, TV power supplies, LED drivers, photovoltaic cells, HVDC production, fuel cells, and wireless power transfer applications. By examining the strengths and weaknesses of the different LLC resonant converter designs, this study aims to contribute to the ongoing research efforts in improving the performance and efficiency of this important power electronics converter.

“…The topology depicted in Figure 4d has the same capabilities. In this case, the Z-source network covers all transmitter tasks by utilizing only one controlled element [28][29][30]. Such topology has two transmitting coils, which enables an increase in the tolerance of the displacement of the receiver.…”

This study proposes an example of a wireless charging station design for a small-scale vehicle available on the market. The article analyzes basic transmitter inverter topologies and their compensation methods in terms of flexibility of control, tolerance to uncertainty in positioning, and the possibility of decreasing the integration price. Our comprehensive analysis focuses on the battery voltage range, energy capacity, cost, and travel distance. We evaluate the constraints of efficiency, transmitted power, amount of used material, and size of the energy delivery system based on our design example. The aim is to increase the penetration of wireless technology in terms of convenience and integration capabilities.
