The 2L- VSI generates eight voltage vectors, six active vectors and two zero vectors, as it is shown in Fig. 1(b). At any instant of time, the voltage vector of the power converter in a...

通过简单地消除钳位FET，就可以解决这一问题，从而产生无处不在的两电平电压源逆变器（2L-VSI）。 2L-VSI只有6个FET，但它可以在任何功率因数下完全塑形线电流，因此它支持双向功率流，谐波失真低。 可以使用三电平NPC和ANPC拓扑，但在这种应用中，它们没有TNPC的优势，尤其是SiC FET的高性能。 使用更高的DC链路电压时，需要更多这类拓扑，例如在具有1500 VDC输入的太阳能系统中。

2023年10月27日 · A new pre-selection strategy for voltage vectors (VVs) is designed based on statistical analyses. This strategy fully utilizes the six non-zero VVs of the 2L-VSI to completely restrict common-mode voltage CMV within ±udc/6.

2022年12月12日 · Theoretical analysis and experimental measurements are conducted in a 2.2 kW heatsink-less 2L-VSI prototype and induction machine, which demonstrates that the minimum switching losses DPWM (MSL-DPWM) is the most favorable solution in practice in terms of the achievable power conversion efficiency and harmonic distortions and also produces the ...

2018年3月15日 · Abstract: In this paper, a direct torque control (DTC) with a variable switching instant is proposed for a permanent magnet synchronous motor (PMSM) fed by a two-level voltage source inverter (2L-VSI). The variable switching instant allows the switching behavior to occur at any instant within one control interval instead of being fixed at the ...

2018年1月1日 · DC-link current is an important parameter for selection and design of DC-link capacitor or battery. Considering the AC current ripple, this study introduced a general DC-link current real-time prediction method for three-phase two-level voltage inverters (three-phase 2L-VSI) using the pulse width modulation.

This paper proposes a modulated model predictive torque and flux control (M2PTFC) method with low complexity for a two-level voltage source inverter (2L-VSI) fed permanent magnet synchronous...
