Abstract :
High power converters (MW) use thyristor arrangements in phase-controlled mode by the voltages of the power supply network. However, low-rank harmonic currents and lagging reactive power are drawn on the AC side. In this paper, a new "dual-switching" mode with GTO switches reverse blocking capabilities is studied and carried out in basic rectifier bridges and naturally commutated cycloconverter topologies. This concept allows cancellation of the reactive power flow between the power supply network and direct converters whatever the load parameters. Global features are given with a final comparison list, especially on the following "dual-switching" topologies: full-bridge cycloconverter, mixed-bridge cycloconverter and series arrangement of full-bridges cycloconverter. Presented experimental results are based on a 20 kVA versatile cycloconverter prototype and confirm the theoretical study. These topologies are expected for a better matching between network and high power converters.
