Wireless energy transfer system for use in underground mining

development work carried out under the HEET II (High Efficiency
Energy Transfer) project, supported by the Research Fund for Coal
and Steel (RFCS). First, the concept of a system for wireless energy
transfer using capacitive coupling is presented. Technically similar
solutions, assumptions, selected results of model tests and main
components of the system are presented, also connections to
cooperating systems are described. An example of a machine
adapted to receive energy from the discussed system has been
shown. Moreover, the selected research aspects, which require
special attention during testing the prototype, regarding the planned
implementation, are detailed. The authors focused on the
experimental determination of capacitive coupling parameters - the
results indicate that it will be possible to meet the requirements of
the power transfer in the planned prototype system.
