Abstract

In this research, a contact-less power station (CLPS) is a power transmission system using a transformer that is constructed with two flat coils facing each other. It transmits power from a supply end to a receiving end without them making contact. This system is maintenance-free because there is no galling of the terminals. It is also suitable for use in harsh environments because it has no naked terminals. We developed a CLPS that is suitable for supplying energy to moving electric loads. <br>In designing the parameters, we aimed to stabilize the output voltage and improve efficiency. We also studied a suitable coil shape to supply energy to moving electric loads. Furthermore, we studied the allocation of capacitors to decrease the difference in current that was generated between each strand wire when coils were made of multiple strand wires. <br>We conducted experiments with a small-scale model that we designed with these viewpoints in mind, and met our target values.
