Using Halbach Arrays for Improving Range and Efficiency of Contactless Wireless Chargers

This paper aims to improve the traditional wireless systems using Halbach array. Drawbacks of traditional wireless systems have been studied and it is found that one of the central problems with current wireless charging systems is its limited range and power transfer inefficiency. These greatly hamper the mobility of the system and causes inconvenience to the user. To improve this, use of Halbach arrays has been proposed which improves the directionality of the charger. A tower-like structure is proposed which can transfer power over longer distances than current wireless chargers which will remove the restriction of the charging device to stay in contact with the charger for efficient charging.
