| Abstract |
The paper presents a new design solution of a power electronic indirect frequency converter with an output power of 1.5 MVA at 3 × 690 V. The supply voltage is 3 × 690 V, frequency control range 2 ÷ 52 Hz. The 3-phase, bridge-type system of the converter was realized with turn-off type IGCT thyristors, with lower power losses as compared with GTO thyristors and more advantageous dynamic properties (short turn-off times). An original cooling system was applied which consists of heat pipes directly carrying away the power losses of the IGCT thyristors. In this way a reduction of the thyristor set volume by 2.5 times was achieved. A microprocessor control was applied together with a diagnostic and monitoring system. The frequency converter is subjected to laboratory tests at present. It can be used for the speed control of induction motors for pump, fan and belt conveyor drives, etc. |
