In order to simplify the commutation in the virtual rectifier, a zero current commutation model predictive control (ZCC-MPC) method is proposed for the induction motor drive system fed by indirect matrix converter (IMC). Switching states combination is adopted in the virtual inverter instead of single predictive switching state, which ensures that the inverter stage keeps at zero voltage vectors during...
In this paper a high performance Direct Torque Control (DTC) theme for the induction motor fed by indirect matrix converter is proposed and investigated. Since the indirect matrix converter has an intermediate dc link, the control process can be separated into rectifier stage modulation and inverter stage modulation. Indirect space vector modulation (ISVM) for input current is applied on the rectifier...
This paper presents a novel Direct Torque Control (DTC) of Doubly-Fed Induction Machine (DFIM) based on Indirect Matrix Converter (IMC). The matrix converter allows many advantages compared to the conventional voltage or current source inverters. Functionally the IMC is very similar to the Direct Matrix Converter (DMC) but it has separate line and load bridges. Indirect matrix converter has no electrolytic...
