Abstract: This paper studied on the dead-time effect for the inverter of permanent magnet synchronous motor servo system. A novel method was proposed for dead-time effect compensation basing on average error voltage. The d-axis (direct) voltage and q-axis (quadrature) voltage were used to determine the sector of the stator current, and compensated voltage was selected to compensate the stator current distortion causing by the dead-time effect.
Key words: PMSM; inverter; compensation of dead-time effect
