2results about How to "Reduced dynamic performance" patented technology

The application relates to the technical field of semiconductors, and discloses a bidirectional semiconductor device control circuit, which comprises a bidirectional device, the bidirectional device being a single-gate bidirectional semiconductor device, and the bidirectional device having a substrate electrode; and a potential adjusting unit connected with the bidirectional device and used for controlling the potential difference between the potential of the substrate electrode and the lowest potential of the bidirectional device to be less than or equal to a first preset voltage value when the bidirectional device is in a certain working state or is switching the working state. The application can effectively improve the dynamic performance and long-term reliability of the bidirectional device.

A method for determining the output rotational speed (nA1, nA2) of the shaft (26) of a machine (27), particularly an internal combustion engine, using a filter, wherein the characteristics of the filter are determined based on the operating characteristics of the machine (27), wherein the characteristics of the filter are the filter length.
