Abstract

The control circuit applies narrow control pulses to the thyristors at the beginning and during the conduction interval and monitors the positive forward voltage. The magnitude of the positive forward voltage acting at the thyristor unit is monitored. The magnitude of the positive forward voltage at each thyristor is monitored. Control signals are generated at the moments when the magnitude of the forward positive voltage at the thyristors exceeds a given limit. The number of control signals is defined. The narrow pulses applied whilst the thyristors are conducting are applied to all thyristors at the moment the number of control signals reaches a given value.
