摘要：
In this paper, a space vector pulse width modulation (SVPWM) strategy for the three-level quasi-switched boost T-type inverter (TL-qSBI) is presented. Under the SVPWM control method, the inductor current ripple of the TL-qSBI is reduced. In the proposed SVPWM technique, the shoot-through duty cycle is maintained constant to keep the modulation index as high as possible. Then, the only control parameters of the TL-qSBI are the duty cycles of the two additional switches. By controlling the duty cycles of the two additional switches, the voltage gain of the qSBT2I can be improved to a value larger than that of the conventional three-level impedance source inverters. The steady-state analysis and operating principles are presented. Simulation results validate the theoretical analysis.
