Abstract: PROBLEM TO BE SOLVED: To prevent rush input current into a converter and make it possible to move the converter to operating condition smoothly by gradually increasing a voltage command to be applied to a control circuit from a low voltage to a specified command when starting to control a power supply for taking out DC power from the sine wave converter. SOLUTION: After turning an electromagnetic contactor MC1 on and charging an electrolytic capacitor 6 for filtering a main electromagnetic contactor 3 is turned on and thereby the voltage control of a sine wave converter is started. At that time, a command switch 13 of a soft start command generator 12 is connected in a non- operating condition and V** is applied to a subtractor 8 by a command voltage from an initial command setting device 15 through a first order lag circuit 14 constituted of a contact 13b, a capacitor C3, and a resistor R3. The output voltage of the subtractor 8 is compared with a corresponding detected voltage Vf and added with an error value by a voltage PI arithmetic circuit and then is gradually increased. After the passage of a specified period of time, the command switch 13 is operated to switch the command voltage to a fixed voltage command 7.  As a result, the converter can be moved to an operating condition smoothly without causing large input peak current to flow since there is now no change in command voltage.

Abstract: PURPOSE:To obtain a torque sensor capable of detecting the direction and absolute value with a high sensitivity, by differentially detecting changes in inductance due to magnetostrictiveness at a multi-thread section with +45 deg. and -45 deg. pitches. CONSTITUTION:A multi-thread 2 is formed on a rotating shaft 1 with a pitch angle 45 deg. and -45 deg. with respect to the thrust direction of the shaft 1. A magnetostrictive Fe based amorphous soft magnetic alloys 3a and 3b are fastened on the thread portions 2a of the multi-thread 2. Coils 4a and 4b are arranged separately outside the alloys 3a and 3b so as to be concentric with the shaft 1. When a right torsion is transmitted to the shaft 1, a strain is generated in an alloy 3b on the +45 deg.-pitched thread portion 2a to reduce the inductance. At this point, the strain generated in the alloy 3a of the -45 deg.-pitch is limited and changes in the inductance is also limited. A differential outputs is obtained between the two coils 4a and 4b at a detection section 5. This produces a torque sensor which capable of detecting the direction of torque and the absolute value with a high sensitivity.
