Latest Patents

Dillig's latest patents include a frequency converter with a DC link capacitor and a method for pre-charging the DC link capacitor. This innovative frequency converter features an AC-DC converter and an inverter interconnected via a DC link. The design includes a first and a second circuit branch interconnected by a DC link capacitor and a commutation capacitor. To protect the AC-DC converter from damage caused by overcurrent, the first circuit branch incorporates a choke. This choke connects a capacitor-side terminal to the DC link capacitor and a switch-side terminal to a DC link terminal of the AC-DC converter via a semiconductor switch. The semiconductor switch is designed to control the magnitude of the electric current flowing from the AC-DC converter into the DC link capacitor based on a control signal.

Another significant patent addresses the identification and blocking of fault currents in frequency converters. This method is crucial for ensuring personnel safety and fire protection. It involves determining the magnitude of a current flowing through the frequency converter and predefining a signal portion that is independent of switching processes while the converter operates fault-free. The method checks whether the determined current course meets a predetermined criterion and interrupts the current if it does not.
