This paper investigates the safety states in two modes, Six Switch Open(6SO) and Three Phase Short(3PS), and describes the behavior of torque and current generated in each state. The transient state and steady state behavior of the current appearing in the active short circuit operation were analyzed. In addition, a conceptual design of a Safety Logic Circuit that can converge to an active short-circuit state even in case of MCU failure was proposed. And the active short-circuit current and braking torque generated during active short-circuit were analyzed through FEM analysis in consideration of the worst case operating conditions and environmental conditions of IPMSM. Finally, considering the back EMF with respect to the battery cutoff voltage and temperature, the time of switching from 3PS to 6SO was also considered. This paper includes the analysis of the ASC-current in transient and steady state by simulation results.
