This paper deals with an adaptive direct torque control (DTC) of two induction motors fed by a Z‐source five‐leg inverter. Indeed, one power common leg is shared between two phases of the two induction motors to reduce the power switches number. Furthermore, an impedance network (inductances and capacitors) is inserted between the DC source and the five‐legs power inverter to boost the input voltage and therefore eliminate a DC‐DC converter floor. In hence, during each sampling time, shoot‐through states are applied alternatively with the DTC techniques to ensure at the same time boost voltage regulation and an independent control of both induction motors. In this context, validation results have been presented to prove the effectiveness of the developed system.

由Z源五脚功率逆变器供电的两个感应电机的直接转矩控制

本文涉及由Z源五脚逆变器供电的两台感应电动机的自适应直接转矩控制(DTC)。实际上,在两个感应电动机的两相之间共享一个功率公共支路,以减少功率开关的数量。此外,在直流电源和五脚功率逆变器之间插入了一个阻抗网络(电感和电容器),以提高输入电压,从而消除了直流-直流转换器的接地层。因此,在每个采样时间内,直通状态可以与DTC技术交替使用,以确保同时进行升压调节和两个感应电动机的独立控制。在这种情况下,已提出验证结果以证明所开发系统的有效性。
