Multifactorial rig for study of inductive powering systems with arbitrary orientation of the coils

The aim of this work was to develop a multifactorial rig for the study of the process of wireless power transfer. This rig must provide means for gathering large amounts of data in an automated way for various types of misalignments, circuit solutions and geometry of the coil couple. For implementation of the rig stepper motors with guidescrews and servo drives with the use of under the control of the microcontroller, and unified frames for the manufacture of the coils were used. The designed multifactorial rig together with the developed software for automated control allows convenient orientation of the coils and provides means for measurement of large amounts of data. Finally, a method was developed for calculating mutual inductance, output power and efficiency without the data from the receiver, and a method for controlling the quality factor of the system powered from a signal generator.
