초록

In this paper, the capacitance properties of degraded thyristor with temperature and voltage were presented. As degraded thyristor, 8 thyristors with each other different reverse blocking voltage used. Its impedance and resistance properties were measured from frequency 100Hz to 10MHz applied with bias voltage from 0V to 40V. As a result, at low frequency region, that is, at the frequency 100 - 10kHz, the abrupt increasement of its capacitance was confirmed. And also, at high frequency region, the capacitance peak move toward low frequency in the region of frequency 4 - 6MHz as degradation of thyristor.
