Abstract
This paper focuses on the functional safety of the electric vehicle drive system. Taking the permanent magnet synchronous motor (PMSM) as the research object, the research on the three-phase current response and suppression of the PMSM in the active short circuit (ASC) mode is carried out. In this paper, a transient analytical model of PMSM is established, and the response of three-phase currents after PMSM enters ASC mode is deduced and analyzed. Then, the influence of the phase angle (\(\delta\))of the PMSM at the moment of ASC on the current peak value Iabc_max is discussed. The real motor controller and motor simulator are used to test and verify, and the results show that \(\delta\) does affect the size of Iabc_max. In order to reduce the impact of excessive current on other devices, the value of Iabc_max should be as small as possible. The mathematical model of the three-phase current after ASC is established in MATLAB, and the \(\delta\) corresponding to the minimum value of Iabc_max is obtained, so it is only necessary to control the motor to enter the ASC at the moment of \(\delta\), the value of Iabc_max can be reduced, and the safety and reliability of the motor controller can be improved.
