Abstract The ultra slim U-I and W-I primary and pick-up coils for OLEV (On-Line Electric Vehicles) are proposed. With the proposed structures, the amount and the cost of the core are dramatically reduced. Not only air gap but also the lateral displacement are improved. The proposed structures are applied to the OLEV bus and SUV, which achieve 83% efficiency at 17㎝ air gap with more than 60㎾ output power, and the construction cost is lower than ₩300M/㎞. The proposed coil structures are verified with simulations and experiments.
