From our understanding about WPT, it is a very advanced technology to transmit energy with indirect connection between source and destination [1]. Lots of applications are implementing this technology, such as: (1) electric vehicles (EV), (2) capsule endoscopy, (3) power supplies (underwater or beneath the earth) and so on without any affection [1], [2], [3]. Power transfer applications demand has significantly increased especially in high power. Basically, the required power level must be handled well by converters to transmit power between primary and secondary sides [4], [5]. The problem is that the semiconductor device limitations limit the latest WPT system [6]. In addition, the low reliability of the WPT system is based on magnetic pairing with a single transmitter and receiver because it only has one energy transmission channel [7]. This is not suitable for applications that require power up to hundreds of KVA to MW. Therefore, WPT applications with various conditions including large incompatibilities must be able to meet the requirements with high efficiency transmission [8]. Lately, EV is one of the most common applications of WPT technology [9]. Abstract: Nowadays, the transportation changes are happening in the Electric Vehicle (EV). Changes are made from cable to Wireless Power Transfer (WPT) as a solution. Current state of the implementation, there is still a misalignment on Power Transfer Efficiency (PTE) because of parking behavior. To overcome the problem, we propose new coil design for better optimization of the PTE. In addition, the new design has better size reduction of receiver (Rx) coil. Our experimental research is about to simulate Rx and transmitter (Tx) designs in simple and small scale of parking situations. The results show that an incremental PTE in the center of the coil, an incremental PTE during misalignment on a radius array, and an incremental PTE during misalignment tangential boundary. We conclude that overall better PTE is achieved compared to single coil design and circular coil arrays.
