In this paper, we propose a speed Permanent Magnetic Synchronous Machine (PMSM) sensorless control technique. The approach is based on the measurement of the DC Bus current. A reconstruction phase current algorithm is developed and presented. This algorithm is mainly based on the switches' control signals of the inverter generated by the SVPWM. However the phase current reconstruction with a standard SVPWM induces some dead zones. So, the measurement of the DC Bus current is not possible due to the fact that the duration time of the active voltage vector is shorter than the minimum time necessary for the current acquisition. To overcome this issue, we propose an Adjusted SVPWM control strategy which allows a reliable reconstruction of the phases currents.
