Abstract

Modular winding structure has been employed in the Permanent Magnet SynchronousMotors (PMSMs) to increase the reliability and reduce the torque ripple. Nevertheless, the reliability ofthe motor system depends on the lifetime of the power semiconductor devices. Since the thermal cycles,which can generate the mechanical stress between the different material layers in power devices, are thekey factors to influence the lifetime of power devices, in this paper, an Active Thermal Control (ATC) formodular power converters in PMSM drive is proposed to extend the system lifetime. The power routingmethod is employed to balance the power in a quadruple modular winding PMSM system. The RainflowCounting Algorithm is used to calculate the thermal cycles with a load mission profile, and estimate thelifetime of the power converters. The proposed method is validated by both simulation and experiments.
