In this paper, we study a new kind of continuous-alternating converters: a seven-level neutral point clamping (NPC) voltage source inverter (VSI). We propose this inverter for applications in high voltage and high power fields. In the first part, we develop the knowledge and the control models of this inverter using the connections functions of the semi-conductors. After that, we present two pulse width modulation (PWM) algorithms to control this converter using its control model. We propose these algorithms for digital implementation. This multilevel inverter is associated to the induction machine. The performances obtained are full of promise to use it in the high voltage and high power fields of electrical traction.
在本文中,我们研究了一种新型的连续交替变换器:七级中性点钳位(NPC)电压源逆变器(VSI)。我们提出这种逆变器用于高电压和高功率领域的应用。在第一部分中,我们利用半导体的连接函数发展了该逆变器的知识和控制模型。之后,我们提出了两种脉宽调制(PWM)算法,以基于其控制模型来控制该变换器。我们建议将这些算法用于数字实现。该多级逆变器与感应电机相结合。所获得的性能在高电压和高功率的电气牵引领域中展示了良好的应用前景。
