The detected value of the detection function (max. detection function) 2 and the detected value of the min. detection function 3 are inputted in an adding function 4 and added. The added value by the adding function 4 is inputted in a dividing function 5 and divided by 2. That is, a mean value of the maximum and minimum of respective instantaneous three-phase voltage commands is calculated by the adding function 4 and the dividing function 5. It is thus possible to increase utilization factor of a DC power source.

Title: Semiconductor acceleration sensor
Inventor: YOSHIDA KEIICHI
IPC: G01P15/12
Filed: 1995-03-28
Abstract: PURPOSE: To protect a cantilever against fracture in the case of application of an undue acceleration. CONSTITUTION: A cantilever 5 supported flexibly at the base part is formed by machining a semiconductor board and a piezoelectric weight part 7 is formed on the cantilever 5. Output from a sensor section 1 provided with the cantilever 5 variable with the acceleration is inputted to a detecting section 2 where the acceleration is detected. When the detected acceleration is higher than a predetermined level, output from the detecting section 2 is fed back to the sensor section 1 through a feedback section 3. The output thus fed back is delivered to the weight section 7 in order to flex the weight section 7 reversely to the cantilever 5.  In other words, when an undue acceleration is applied to the cantilever 5, a voltage is applied to the piezoelectric weight part 7 in order to flex the weight section 7 reversely thus relaxing the stress caused by the flexure of the cantilever 5 and protecting the cantilever 5 against fracture.
