  1. Choosing High-Frequency Ferrite Tiles for Wireless Power Transfer Systems

  2. Wireless Power Transfer (WPT) technology is used to wirelessly transfer electrical energy from a transmitter to a receiver. With recent advancements, this technology is gaining popularity for usage in electric car chargers, robotics, medicinal devices, and other applications. It has the advantages of dependability, efficiency, adaptability, and ease of maintenance. Because of the galvanic separation, this kind of charging has a lesser danger of electrical shock. www.cosmoferrites.com

  3. Wireless Power Transfer Work WPT technology transfers electric power through the air gap without using wires or cables. It uses the principle of magnetic induction, which is based on Faraday’s law of induction. As per the law, if there are two magnetically coupled coils, then the AC current passing through the transmitter coil will spark a voltage in the receiver coil. The voltage generated can be utilised to power electrical equipment. There is no physical connection between the transmitter and receiver coils during the whole power transmission operation. The only way for power to be transferred is through magnetic fields.

  4. Role of Ferrites in Wireless Power Charging Systems One of the reasons that WPT has not been widely used in the automotive and manufacturing industries is its low power conversion efficiency. Magnetic flux in typical WPT systems is absorbed by the metal casing and does not pass through the receiver. As a result, power losses increase and power efficiency decreases. This causes excessive heat, which can damage the components and provide a safety risk to the system operator or end user. Furthermore, at lower working temperatures, these systems produce large core losses.

  5. Ferrites are being used in the WPT system owing to the following reasons: • Higher charging efficiency • Higher operating frequency • Wider operating temperature • Suitable for high power WPT Systems WPT systems with ferrites reduce electromagnetic interference between the antenna and the metal enclosure. To improve charging efficiency, magnetic flux is maintained between the transmitter and receiver coils. As a result, ferrites limit magnetic energy leakage in metal housings. Furthermore, these systems can charge at ambient temperature with excellent efficiency.

  6. Precautions to take while choosing Ferrites for WPT • Mechanical Stress & Shock • High Temperatures • Strong Attractive Force • Initial Permeability
