Compensated synchronous PI current controller in overmodulation range and six-step operation of space-vector-modulation-based vector-controlled drives. IEEE Transactions on Industrial Electronics 49 (3) : 574-580. ScholarBank@NUS Repository. https://doi.org/10.1109/TIE.2002.1005382 | Abstract: | Overmodulation enhances the power utilization of the installed capacity of a voltage-source inverter. A space-vector strategy is used for constant-switching-frequency inverters. In order to achieve the overmodulation, a modified reference signal with nonuniform angular velocity is generated using a preprocessor. Such a reference wave produces low-frequency harmonics in currents. The presence of current harmonics restricts the bandwidth of the synchronous proportional plus integral current controller in the overmodulation range. A compensating current control is presented to allow for high-bandwidth current control in synchronous coordinates during overmodulation and six-step. The proposed scheme allows for an easy upgrade of a conventional vector control scheme to include overmodulation and, thus, reduce the design-to-market time. | Source Title: | IEEE Transactions on Industrial Electronics | URI: | http://scholarbank.nus.edu.sg/handle/10635/55360 | ISSN: | 02780046 | DOI: | 10.1109/TIE.2002.1005382 |
