Abstract
- A novel space vector modulation (SVM) strategy called maximum-boost discontinuous SVM (MBDSV) is proposed in this paper to reduce the thermal stress of three phase impedance source inverters (ISI). By exploiting the switch clamping mechanism and arranging the shoot-through (ST) states properly, the proposed strategy obtains the flowing merits: further optimize the thermal performance, improve the reliability, reduce the current stress and maximize the dc-link utilization of ISI. The proposed MBDSV was compared to the existing modulation strategies and the feasibility of the MBDSV had been benchmarked by simulation and experiments. • Thermal optimized space vector modulation strategy for impedance source inverter. • Discontinuous SVM is developed to reduce the thermal stress of inverters. • Suitable for medium or high output frequency applications • Simulation and experimental tests are carried out with three-phase qZSI.
