Abstract

PURPOSE: To prevent an input transformer and a DC reactor from being overheated by setting up a temperature monitoring device in either of the input transformer or the DC reactor or in both.
CONSTITUTION: When an overheated state occurs and the temperature of an input transformer 1 and a DC reactor 3 exceeds the preset temperature, the temperature detection signal by temperature monitors 15 and 16 enters a current regulator 12. This current regulator 12 first operates a rectifier 2 before the control by the main loop 18 and supplies the signal to limit the output of the rectifier 2 through a dode 14.
