Analyzing Method for Characteristics of Thyristor Converter Used in AX Invenrter Rolling Stock

Abstract

Simulation methods are widely used to analyze a non-liner circuit like a thyristor converter. Those methods are useful to study on behavior of the non-liner circuit. However, the methods need the long time to obtain the results. This is because the current and voltage waveforms should be calculated repeatedly in a very short interval for accurate results. It takes too long to study on main circuit constants by the simulation methods, in which there are many cases to calculate. Therefore, a method which enables to analyze the characteristics of the thyristor converter easily and shortly will be needed to design the circuit constant. This paper proposes a new method to analyze a thyristor converter used in the AC inverter rolling stocks easily and shortly. Also, analysis results show the effectiveness of the method.
