Abstract
In order to check the functionality of a conventional current converter at low cost, a device for checking a current converter is provided. The current converter includes a test current conductor and a test pulse circuit. The latter has an energy storage device, a charging device for charging the energy storage device and a switching element for discharging the energy storage device via the test current conductor. As a result, a discharge current can be generated in the test current conductor, wherein an evaluation unit for detecting a current converter signal caused by the discharge current is provided.
Claims18
1-17. (canceled)
A device for checking a current converter, comprising:
- a test current conductor;
- a test pulse circuit connected to said test current conductor, said test pulse circuit having an energy storage device, charging means for charging said energy storage device, and a switching element for discharging said energy storage device through said test current conductor for generating a discharge current in said test current conductor;
- and
- an evaluation unit for detecting a current converter signal caused by the discharge current.
A method for checking a current converter, which comprises:
- guiding a test current conductor at least once through the current converter and then connecting the outputs of a test pulse circuit to one another by way of the test current conductor;
- charging an energy storage device;
- subsequently actuating a switching element to discharge the energy storage device, and generating a discharge current flowing over the test current conductor;
- and
- measuring a current converter signal generated by the current converter as a result of the discharge current.
