Impact of DC-Link Voltage Imbalance on Modulation Accuracy in Dual Inverter Systems
Original language description
This paper investigates the impact of DC-link voltage imbalance on the output voltage accuracy of Dual-Inverter (DI) topologies, which are increasingly relevant in highperformance electric mobility systems due to their efficient DCbus utilization and potential for switching loss reduction via advanced modulation techniques. A modulation strategy that clamps one inverter and modulates the other is analyzed, with attention given to its assumption of equal DC-link voltages. It is shown that voltage asymmetry distorts the inverter voltage hexagon, leading to significant errors in synthesized voltage vectors and introducing waveform discontinuities. Analytical expressions for these errors are derived and validated through simulations, highlighting the limitations of conventional modulation approaches and the need for improved strategies under non-ideal conditions.
