50 kW eddy current brake

Abstract

The project involves the refurbishment of the “Heenan-dynamometer” located underneath S block at the University of Southern Queensland. The current system does not allow any computerized data acquisition. Upgrading the electronic control unit using solid state power electronic devices will enable users to perform better tests on engines and in the near future, it will allow the user to acquire digital data via a computer. The actual dynamometer control unit uses valve technology to rectify the AC source and control the system output. The upgraded system will perform the same operation however is will use solid state devices. In order to use the new system on the dynamometer, a protective circuit based on pre-established conditions has been designed.
