Abstract in different language:	In present time the high efficiency switching DC/DC converters, e.g. buck and boost are often used. This work describes some problems of DC-DC converters, which can occur, when the load is suddenly disconnected or simultaneous disconnection of the load and the capacitor at the output. The results were derived both by simulation but also by measurement. A special measuring system has been developed for these measurements, which enables the realization of fault conditions. Therefore, measurements were performed on 2 different types of DC-DC converters. The results of simulations and measuring are presented in the work. Error conditions usually cause an overvoltage that can damage the equipment connected to the converter. A solution how to prevent overvoltage and thus damage connected systems is also described.
