Abstract :
The forward breakover voltage and forward conduction voltage drop of a thyristor have been measured as a function of decreasing temperature between 25°C and -180°C. These data are presented for a 1200-V, 560-A average, inverter thyristor. Both the measured and calculated forward breakover voltages exhibit negative temperature coefficients. The decrease in VBF at low temperatures necessitates that thyristors with overrated blocking voltages be used at these temperatures
