It was shown that the mean value of the holding current in the thyristors with thin anode was significantly higher (0.7A) than that of the thyristors with thick anode (0.1A), while other parameters had practically the same values. The open circuit voltage decay (OCVD) method was used for ...
A power converter coupled to the rectifier receives the rectified DC voltage and generates a controlled output current. A damping circuit coupled to an output terminal of the rectifier includes a damping resistor for maintaining the holding current in the thyristor during an ON period of the ...
