In this study, a compound control strategy for motor side and quasi-Z source is proposed to improve the robustness of permanent magnet synchronous drive system subjected external disturbance. method, complementary sliding mode as feedback controllers are combined with disturbance observer technology feed-forward compensator achieve fast tracking suppression PMSM system. Firstly, signal models i...

This paper proposes a three-level diode clamped active impedance source inverter (AIS-TLI) based on the quasi Z-source (qZSI). Apart from having minimal components and inherent benefits of qZSIs, such as single-stage buck-boost capability, shoot-through (ST) immunity, continuity input current, proposed topology has higher boost capability excellent efficiency. In addition, bridge modulation ind...
