A SVPWM Method Based on Z-Source Three-Level Inverter

Article Preview

Abstract:

Compared to the traditional dual Z-source inverter, Z-source inverter with a signal X-shaped LC impedance network has advantages of lower cost and an easier modulating algorithm. Based on the three-level single Z-source inverters, this paper proposed a suitable SVPWM scheme, which include vector region judgment, send order determine, and synthetic time calculation. It is available to achieve inductive voltage boosting by inserting the shoot-through vectors appropriately, while simultaneously provide a good performance on output with a correct volt-second average. The theoretical concepts discussed are verified by simulation results.
