| Abstract |
Several proposals have been published to combine the principles of operation of the cycloconverter (CC) and of the current-source-inverter (CSI) in large power adjustable speed drives with synchronous motors. Converters allowing such a combination can be referred to as "CC/CSl-converters". The objective of this research has been to overcome the well-known difficulties of the load-commutated current-source-inverter at standstill and at low speeds (torque ripple and unsufficient commutating voltage). In this paper a novel control strategy is described for a CC/CSl-converter feeding a synchronous motor with six stator windings. This novel control strategy is compared to a control strategy previously published, where the same CC/CSl-converter feeds a usual synchronous motor with three stator windings. A first industrial application of a CC/CSI-converter drive will be described. |
