Magnetocaloric effects of various materials are getting more and more interesting for the future, as they can significantly contribute\ntowards improving the efficiency of many energy intensive applications such as refrigeration, heating, and air conditioning.\nAccurate characterization of magnetocaloric effects, exhibited by various materials, is an important process for further studies and\ndevelopment of the suitable magnetocaloric heating and cooling solutions.The conventional test facilities have plenty of limitations,\nas they focus only on the thermodynamic side and use magnetic machines with moving bed of magneto caloric material or magnet.\nIn this work an entirely new approach for characterization of the magnetocaloric materials is presented, with the main focus on a\nflexible and efficient power electronic based excitation and a completely static test platform. It can generate a periodically varying\nmagnetic field using superposition of an ac and a dc magnetic field.The scale down prototype uses a customized single phase Hbridge\ninverter with essential protections and an electromagnet load as actuator. The preliminary simulation and experimental\nresults show good agreement and support the usage of the power electronic test platform for characterizing magnetocaloric\nmaterials.
