Abstract: This paper proposes a standstill test method for the determination of electrical parameters of permanent magnet synchronous machine (PMSM) drive system fed by a conventional three-leg inverter. In order to estimate the equivalent total circuit resistance, a self-cancellation method is proposed to eliminate the influence of inverter nonlinearity on the calculation. With the identified equivalent total circuit resistance, the voltage drop due to the inverter nonlinearity can be calculated afterwards. In addition, a method to derive the dq-axis inductances from high frequency zero mean dq-axis currents is proposed, which does not need the aid of any complex parameter identification algorithm. The proposed method is finally evaluated on a PMSM experimentally and shows quite good performances in the determination of electrical parameters of drive system.
