We propose two new coil topologies for a contactless battery charging platform. The new topologies consist of square printed circuit board (PCB) coils, grouped in two layers on a PCB. We compare the new topologies to each other and to a previously published topology that consists of three layers of hexagonal coils. For each topology, the magnetic flux density is calculated above the coil layers. In addition, the position dependence of the flux linkage between the primary coil array and a secondary coil is simulated and compared for all three topologies. For one of the new topologies, we compare the simulations with measurements.
