Abstract :
Some aspects of the feasibility of three-level voltage source GTO inverters in HVDC applications are discussed. After presenting the converter topology a simplified point-to-point transmission with a conventional thyristor rectifier station and a three-level voltage source GTO inverter station is simulated using EMTP (ElectroMagnetic Transient Program). The static behaviour and some aspects of the dynamic behaviour of the transmission are shown. Problems and open questions to be solved in future are mentioned. The results show that the three-level voltage source inverter is a possible alternative for future use of forced commutated inverters in HVDC systems
