Prof Willie Cronje


Prof. Cronje joined Wits in 2004 as professor in the chair for electrical machines and drives. Since 2004 he has spearheaded the renewable energy research effort in the School of Electrical and information Engineering. In recent years at Wits his research has included renewable energy systems based on PV, wind and ocean waves. He supervised a PhD looking into a novel double cylindrical permanent magnet synchronous generator that holds great promise for direct conversion of wave motion into electrical energy. He is currently the holder of the Alstom Chair for Clean Energy Systems Technology in the School of Electrical and Information Engineering at the University of the Witwatersrand.

Prof Ivan Hofsajer


Dr Hofsajer is currently an Associate Professor in the School of Electrical and Information Engineering at the University of Witwatersrand, Johannesburg. His interests include the use and conversion of electrical energy, where the line between electromagnetics and circuit approaches starts to blur. This often occurs when the performance levels of electrical systems are increased, through high levels of optimisation or extension of operational lifetime. He has published over 100 journal and conference papers in this area.
