A rectifier switch has a plurality of series-connected thyristors, the forward and reverse blocking voltages of which exhibit a large spread of at least 10%. A plurality of voltage limiting elements are disposed to shunt the plurality of series-connected thyristors to match the distribution of maximum voltages occurring during operation of the plurality of series-connected thyristors to obtain full utilization of the blocking capability of the thyristors.
