Abstract

Within many sensorless driving methods of Switched Reluctance Motors(SRMs), the method that injecting high frequency voltage pulses into unenergized phase windings is easy to implementation. In this paper, we propose a sensorless driving method based on the impressed voltage pulse but using new digital techniques: a digital peak detector and a new digital PLL. The total system is constructed by digital device: Field Programmable Gate Array (FPGA) that is considered cheaper and higher speed compared with DSP. Test results show the possibility of attaining a higher performance level as compared with present approach.
