Problems solved by technology

In contrast to normal thyristors which are now designed, for example, for currents up to 2.2 kA and higher and for voltages up to 7 kV and higher, GTO thyristors can now only be designed for lower currents and voltages and are more expensive of

Embodiment Construction

[0072] figure 1 A schematic structure of the regulating transformer 1 is shown. The regulating transformer 1 consists of a regulated primary side 1a and a secondary side 1b. The primary side 1a comprises the main winding 2 and the switching module 5 . The secondary side 1 b includes a secondary winding 3 . The switching module 5 comprises a regulating winding 8 and switching elements 61 , 62 , 63 , 64 . The output voltage vsek dropped at the secondary winding 3 is a function of the input voltage vprim at the primary side of the regulating transformer 1 and the transformation ratio of the regulating transformer 1 . The transformation ratio of the regulating transformer 1 and thus the output voltage vsek can be influenced via the connection of the main winding 2 to the regulating winding 8 . In order to delimit regulating winding 8 from main winding 2 , three possible configurations are produced by means of switching elements 61 , 62 , 63 , 64 . In a first configuration, th...

Abstract

The invention relates to a method for controlling a switching module based on thyristor switching elements. The invention relates, in particular, to a method for controlling at least one switching module wherein the switching module consists of a first commutation cell and a second commutation cell which are receptively associated with a control winding of a control transformer by means of a firstterminal and a second terminal. Each switching module is provided with an input line and an output line.

Description

technical field [0001] The invention relates to a method for controlling a switching module based on thyristor semiconductor switching elements. In particular the invention relates to a method for controlling at least one switching module, wherein said switching module comprises a first commutation unit and a second commutation unit, said first and second commutation units being respectively The regulating winding of the regulating transformer is assigned via the first terminal and the second terminal. Each switch module is provided with a feed-in line and an output line. Background technique [0002] The document “Control of Thyristor-Based Commutation Cells” published in the category of IEEE Energy Conversion Congress und Exposition (Raleigh, NC, USA, Sept. 2012) describes a method for controlling commutation cells. The described system arrangement comprises a transformer comprising a primary side consisting of a main winding and a regulation winding and a secondary side...
