    摘要： A capacitor precharge circuit limits both peak DC link current and peak AC line current to any desired peak magnitude thereby providing for optimum precharge control and robust operation. The precharge circuit employs a microprocessor which implements a non-linear discontinuous current control scheme without the need for current sensors. The precharge circuit is well suited for use with an AC to DC converter having link inductor and a DC bus capacitor which requires precharging before full power is applied to the converter.

    摘要： A bus bar having reduced parasitic inductance and equal current path legends. A bus bar of the present invention has a first plate connected to a collector of a first transistor, a collector of a second transistor, an emitter of a third transistor and an emitter of a fourth transistor; a second plate including a second plate input connected to a collector of the third transistor and a collector of the fourth transistor; a third plate including a third plate input connected to an emitter of the first transistor and an emitter of the second transistor; and a fourth plate which is connected to the first plate. The first plate, the second plate, and the third plate are disposed such that the lengths of the current paths from the fourth plate through the first transistor to the input of the third plate is equal to the length of the current path from the fourth plate through the second transistor to the input of the third plate. Similarly, the current path from the fourth plate through the third transistor to the input of the second plate is equal to the length of the current path from the fourth plate through the fourth transistor to the input of the second plate. A bus bar of the present invention has many advantages including reduced parasitic inductances, equal current path lengths, ease of construction, the ability to keep parallel transistor operating temperatures equal, and the inputs and output being located on the same side of the bus bar.

    摘要： The present invention relates to a method and apparatus for a two-piece box construction which is a continuous, in-line process in which a pair of panels or blanks are fed simultaneously from one end of the apparatus and move along a substantially linear path through the apparatus where they are joined together so that upon exit from such apparatus the joined blanks can be fed directly, in line, into a conventional folder/gluer apparatus for final folding, gluing and other processing.

    摘要： A bus bar having reduced parasitic inductance and equal current path lengths. A bus bar of the present invention has a first plate connected to a collector of a first transistor, a collector of a second transistor, an emitter of a third transistor and an emitter of a fourth transistor; a second plate including a second plate input connected to a collector of the third transistor and a collector of the fourth transistor; a third plate including a third plate input connected to an emitter of the first transistor and an emitter of the second transistor; and a fourth plate which is connected to the first plate. The first plate, the second plate, and the third plate are disposed and arranged such that the lengths of the current paths from the fourth plate through the first transistor to the input of the third plate is equal to the length of the current path from the fourth plate through the second transistor to the input of the third plate. Similarly, the current path from the fourth plate through the third transistor to the input of the second plate is equal to the length of the current path from the fourth plate through the fourth transistor to the input of the second plate. A bus bar of the present invention has many advantages including reduced parasitic inductances, equal current path lengths, ease of construction, the ability to keep parallel transistor operating temperatures equal, and the inputs and output being located on the same side of the bus bar. Additionally, a method of increasing converter efficiency is disclosed. The method comprises providing equal length current paths and planar structures that reduce parasitic inductances and maintain equal current sharing and temperature characteristics.

    摘要： An improved power drill having means for sensing when the drill bit has penetrated through the workpiece and for then retracting the drill bit from the workpiece. An electrical signal responsive to the axial force between the drill and the drill bit is used to sense when the drill bit pierces the workpiece. A sudden decrease in the axial force triggers a mechanism for retracting the drill bit from the workpiece. Means are included to detect broken bits, missing bits and previously drilled holes.
