The goal of this bachelor thesis is to reduce the voltage fluctuations in a dynamic inductive power transfer (DIPT) system, by determining the optimal coil location and/or spacing. In a segmented DIPT system the output voltage changes as the receiver (Rx) side moves over the transmit (Tx) side. By analyzing the spacings between the Tx- and Rx-coils it is possible to influence the output voltage and its fluctuations. The system studied consists of two rectangular Rx-coils in series, and multiple bipolar Tx-coils.

This research starts by building a model in COMSOL with one Tx- and one Rx-coil. Then a MATLAB program is presented which can simulate the whole system by, among others, phase shifting the original COMSOL data. Finally, the optimal coil location can be determined by comparing the average output voltage and the fluctuation in output voltage for different Tx- and Rx-coil spacings. Different tests are performed to confirm the results of the COMSOL model and the MATLAB simulations. The research showed that this system can not effectively reduce the voltage fluctuations, therefore a parallel configuration of Rx-coils is proposed. Simulation results show that this alternative solution can reduce the voltage fluctuations.
