Abstract The research described in this paper concentrates on the development of an electronic converter. Successful completion of this converter provides the final component for the larger electric bicycle project. The controller developed for the bicycle is rated at 400 W and is hard-switched. It uses MOSFETs as power switching devices. There are three Hall effect sensors placed 120 electrical degrees apart from each other in the motor for velocity and position sensing. The torque generated by the machine is controlled by hysteresis band current control. In order for the motor/controller to be commercially viable, particular attention was paid to the costs of the controller. The result, an efficient yet cheap controller. Measurement of efficiency is difficult in high performance power electronic controllers [Patterson DJA very high efficiency controller for an axial flux permanent magnet wheel drive in a solar powered vehicle. 2nd IEEE International Conference on Power Electronics Drives and Energy Systems for Industrial Growth, IEEE PEDES ’98, Perth, 30th November–3rd December, 1998.]. The paper includes discussion of a calorimetric method for measurement.
