Analysis of DC Link Current and Voltage Stress for Motor Drive Application in Dual Three-Phase Configuration
Paper i proceeding, 2020

In automotive applications both space and operational safety of the drive-train are important design considerations. In this study a thorough DC link design for a fault tolerant dual three-phase drive train is conducted. PWM interleaving technique is utilized and based on the three-phase reference case DC link sizing maps in terms of both current and voltage stress are obtained for dual-three-phase configurations.It is found that current stress of the DC link capacitor can be reduced by up to 46 % compared to the three phase case. Similarly, the voltage stress can be reduced by up to 45 % while maintaining fault tolerant capability.
