<p>A thyristor matrix arrangement having four columns, each column being formed of n thyristors connected in series with each other. In one embodiment, the series connected thyristors in respective columns are coupled to one another via heat sinks. The thyristors in each column are poled such that forward conduction current cannot flow through only one of the columns. The heat sinks are cross-connected among the columns to form a current path which is formed of appropriately poled thyristors in different ones of the columns and the column cross-connections. The cross-connections are inductive so as to provide relatively large inductive voltage drops when the thyristors are fired, thereby enabling the firing of thyristors having relatively low firing and forward voltages.</p> |
