DC-TO-DC VOLTAGE CONVERTER, VOLTAGE SUPPLY DEVICE, AND DIAGNOSTIC METHOD FOR A DC-TO-DC VOLTAGE CONVERTER

摘要

The invention relates to the diagnosis of the switching elements in a bidirectional DC-to-DC voltage converter. By charging a capacitor in the DC-to-DC voltage converter and then specifically actuating the switching elements and evaluating the voltage in the charged capacitor of the DC-to-DC converter, it is possible to identify a faulty switching element.
