 Abstract

This paper proposes a cost-effective and reliable circuit configuration for active power decoupling in dual-inverter-fed openend winding motor systems. Compared to separately installed active power decoupling circuits, the proposed configuration and control method that utilizes mode switches minimizes the number of components and prevents lifetime imbalance of the inverters by alternating their use every cycle while maintaining low voltage ripple. Junction temperature analysis of the power devices further indicates this approach can prevent lifetime imbalance and rapid aging of the dual-inverter system, resulting in enhanced overall system reliability. The effectiveness of the proposed configuration and control method is validated through a MATLAB/Simulink model and experimental tests using a digital signal processor.
