Abstract
A method for monitoring a power electronic assembly is improved to be more effective and versatile. It includes converting and/or modifying an electrical input into at least one electrical output by a conversion and/or modifying process which proceeds in connection with the power electronic assembly. During the conversion and/or modification a bit stream is generated by a delta-sigma modulator and represents the electrical value, that is to say the electrical input or the at least one electrical output. One bit stream each can also be generated by a plurality of delta-sigma modulators and represents the respective electrical value, that is to say the electrical input and the at least one electrical output. The power electronic assembly is monitored based on the one bit stream(s) thus generated and available as a result. The bit stream(s) is/are not demodulated, and therefore very meaningful information of the corresponding useful signal is provided.
