This paper presents a cost-efficient closed loop control of a small permanent magnet machine for pumping application. The special feature of the described solution is only one current probe in the DC-Link of the converter. The three phase currents are calculated from this measured current in combination with the state of semiconductors at the time of measurement. Near the sector borders of the space vector modulation the turn-ontime of one semiconductor is too short for measuring the current. Adoi:10.1109/iemdc.2005.195720 fatcat:rz2wyfjjfzhfdlopzccalyikva
