“…Inductive Wireless Power Transfer (IPT) has many applications, including electric vehicle (EV) charging. Thongpron et al, [122] has developed a 10 kW IPT prototype for EV charging. The prototype employs a resonant converter to match the impedance of the transmitting and receiving coils, improving power transfer efficiency.…”

Wireless Power Transmission (WPT) has emerged as a prominent player in numerous industries recently. It is already established in wireless charging for electric cars and electronic gadgets. However, it has promising applications in medical implants and imaging as well. Among several proposals, Inductive Power Transfer (IPT) and Acoustic Power Transfer (APT) have shown a major impact on this area of interest. This paper presents a comparison between IPT and APT for wireless power transmission (WPT). Most recent proposals are reported, and several key parameters are considered to evaluate the proposals. That includes operating frequencies, separations gaps, powers and power transmission efficiencies and experimental validity. It is found from the review that; a maximum 818 kW of power is transmitted using IPT for electric vehicles. However, APT can transmit 1.068 kW and 5.4 W through wall and in-body medium (implants). Over 90% efficiencies are found for both APT and IPT. In fact, power transfer with 95.66% efficiency over a 6 cm distance of 23.4 W is achieved for APT and 95.6% with 20 cm separation gaps is achieved for IPT for 20 kW power. A wide range of frequencies are applied for both APT and IPT. However, lower frequencies are mostly suitable for high power, more specifically less than MHz ranges. Naturally, lower frequencies are preferable for low power high efficiencies.

“…An inductive wireless charging station prototype was successfully experimented in Thailand, which could achieve an efficiency of 90% with the use of Litz wire (a type of wire that has several strands of thinner wires) in both transmitting and receiving coils [17]. Wireless power transfer was simulated using Ansys for various coil geometries to calculate their efficiency, coupling coefficient and mutual inductance.…”

The hassle of using plug-in charging for electric vehicles (EVs) such as connecting charger to the port of vehicles, risk of getting electrocuted during rain, dirty and oily charging cable etc. can be eliminated using wireless/induction power transfer (IPT). It can be made smart and automated. Hence, IPT can be considered the future of EV charging. However, the technology is just emerging and there are a lot of limitations at present. The major problems are less efficiency caused by coil misalignment and air gap, and the electro-magnetic field generated around the coils which possesses greater risk for human health. These can be improved by selecting the types of coils and shields which produce maximum magnetic flux between the coils whereas reduce the flux outside the coils. In this research, the strength of magnetic fields produced by various types of coils (circular, square and hexagonal) were simulated in Ansys Maxwell 3D to understand their features and to know which coil is the best for high power transfer efficiency. Similarly, the effects of using ferrite and aluminum shields for leakage reduction, by varying their thickness, were studied. Finally, the leakage flux values were simulated at very high currents to understand their behavior in such conditions.

Wireless electric vehicle (EV) charging is an important operation for valuable EV options in modern life. Inductive wireless EV charging needs constant current and voltage (CC–CV) charge controllers. This paper presents 750 W variable frequency CC–CV inductive wireless charging for an e-golf cart 50 Ah 72 V Li-ion battery. Due to this system’s low power, the system’s efficiency may be weak; the secondary-side (SS) maximum efficiency-controlled (MEC) converter was validated. The golf cart’s battery characteristics were evaluated to design and experiment with inductive wireless power transfer (IPT) coils and an integration system for a 42 kHz resonant frequency. The CC–CV charged control is an infrastructural part of the H-bridge inverter at varied frequencies from 50 kHz to 56 kHz when the DC input voltage is 310 V, and in the range of 44 kHz to 46 kHz at the 155 V input. The results found the charging of 9 A CC, 82 V CV and 730 W. The 310 V input voltage system without the SS MEC converter’s efficiencies was 62% to 72% and it was improved to 65% to 81% using the SS MEC converter. Finally, the best cases were validated at the 155 V DC input voltage and the system with the SS MEC converter had 76% to 86% efficiency.
