DIODE MONITORING

摘要

The invention concerns a method and device for the monitoring and/or protection of high-current diodes, in particular those used in welding equipment, the diode being monitored by determining the temperature (9) of the diode (10) by electrically simulating (UT) the diode temperature (T), preferably by means of an RC network, and then comparing it with a highly reliable temperature reference signal (UR).
