Inventor: OURA HITOSHI
IPC: H02M7/537
Filed: 1994-09-20
Abstract: PURPOSE: To reduce power consumption and to reduce a chip area by connecting a capacitor between the gate of the MOSFET for gate shortcircuit of a bipolar transistor and the collector of the bipolar transistor. CONSTITUTION: When a transiently changing voltage is applied between the collector and the emitter, a displacement current flows between fixed potential V0 and the emitter electrode of an insulating gate bipolar transistor(IGBT) 1 via the capacitor 3 and the gate and source electrodes of the MOSFET 2 for gate short-circuit. The gate parasitic capacitances 8, 9 of the FET 2 are charged by the displacement current, which connects electrically the drain electrode to the source electrode. While, the parasitic capacitances 6, 7 of the IGBT are also charged. An electric charge which charges the parasitic capacitances is discharged via the FET 2. Therefore, the gate voltage of the IGBT is not increased, which excludes to turn, on the IGBT, and the displacement current flows only when the voltage changes. which reduces the power consumption.

Abstract: PURPOSE:To remove the variation of tension synchronizing with rotation and to make a stable winding under a fixed tension by correcting the range of turning angle relating to the correction of tension according to the change of a coil diameter and a rotating speed. CONSTITUTION:A winder (an unwinder) 3 is driven by an electric motor 4, information of rotation of a rotation detector 12 is inputted to a tension controller 11 and the coil diameter and the rotating speed at that time are calculated by a prescribed arithmetic means. When a coil diameter is changed, the range of rotating angle generating the variation of tension is changed, accordingly, a predicted value is calculated by shifting the range of the rotating angle according to a coil diameter and this value is inputted into an electric controller 14 to control the motor 4. Similarly when a rotating speed is changed, the range of the rotating angle generating the changes of tension is corrected ahead of time to remove the lag of control.
