POWER CONVERTER COMPRISING A SWITCHING DEVICE

摘要

Disclosed is a power converter comprising an electric power source that is disposed in series with a switching device. The switching device is fitted with a switching element and an additional electrical element that is arranged parallel to the switching element. Dangerous arcs can be generated when great loads are disconnected at a high voltage and a high current intensity. In order to ensure that the power converter can be safely disconnected from a voltage source, the additional electrical element (7, 10, 11) is configured as a fuse (7), temperature-independent resistor (10), or capacitor (11).
