ANALYSIS ON THE OPERATION PARAMETERS OF THE NEW CONVERTER TRANSFORMER

Abstract

This paper presents a new converter transformer which is applied in multipulse diode/SCR rectifiers/inverter. Comparison of operational characteristics of a conventional converter transformer and the proposed transformer was studied. Results show that the new converter transformer can not only decrease the grid side current, increase the valve side voltage but also greatly reduce the harmonics of the grid side currents. Simulation results verify the correctness of the theoretical analysis.
