Flexible coils become nowadays more and more interesting for inductive power transmission. These coils can be principally used on the transmitter side and the receiver side. However, the flexibility can affect the transmission behavior by the variation of the coil self-inductance and the coupling factor due to deformations. Controlling the IPT system to compensate coil parameters variations during charging processes becomes thereby a necessity. The charge control can be principally by variation of the working frequency, the compensation capacitor value, or the supply voltage level. In this paper, different control methods have been applied on flexible coils. For this purpose, a simulation-based on an analytical model is carried out to investigate the system behavior for different parameters. Thereby, the receiver coil has been considered flat where the transmitter coil is bent in concave and convex directions. The results show that the variation of the supply voltage delivers better results and ensure a constant power while the flexible transmitter is an extreme bending angle.
