Abstract
A method of detecting whether a deficiency is present in a system includes providing electrical energy to semiconductor switches of a controller in the controller system; measuring a direct current voltage across each of the semiconductor switches in the controller; and detecting that the deficiency is present, if the direct current voltage measured across any of the semiconductor switches is higher or lower than a threshold voltage.
Claims20
A method of detecting whether a deficiency is present in a system, the method comprising:
- providing electrical energy to semiconductor switches of a controller in the system;
- measuring a direct current voltage across each of the semiconductor switches in the controller;
- and
- detecting that the deficiency is present, if the direct current voltage measured across any of the semiconductor switches is higher or lower than a threshold voltage.

A controller of a system, the controller comprising:
- a memory;
- and
- processing circuitry configured to detect whether a deficiency is present in the system by,
- providing electrical energy to semiconductor switches of the controller,
- measuring a direct current voltage across each of the semiconductor switches in the controller, and
- detecting that the deficiency is present, if the direct current voltage measured across any of the semiconductor switches is higher or lower than a threshold voltage.
