Title: Power converter
Inventor: HOSHI KIMIHIRO
IPC: H02M7/5387
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To suppress dv/dt and an overvoltage and hence prevent a power element with a large dv/dt resistance from being damaged by constituting an RCD snubber circuit and a clamp snubber circuit with an capacitor, a diode, and a resistor. SOLUTION: A current flowing to an IGBT 5a is absorbed by a capacitor 2a, via a diode 3a of an RCD snubber circuit. On the other hand, a voltage increase dv/dt is suppressed by the charging of the capacitor 2a. As a result, a high voltage and a high current are applied simultaneously, so that these is no possibility of the IGBT from being damaged. Then, an overvoltage inducted by a wiring inductance 6 due to the breaking of current is suppressed by a clamp snubber circuit. A capacitor 2b operates as a capacitor for an overvoltage that is equal to or more than a circuit voltage. In other words, the energy of the wiring inductance 6 is charged into the capacitor 2b, thus suppressing an overvoltage due to the wiring inductance.

Title: Pulse motor driving device in aligning device for sheet- like material
Inventor: SAKAI KATSUHIDE
IPC: H02P8/38
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To set a most suitable current value in response to load without directly detecting the load applied to a pulse motor. SOLUTION: A pulse motor M1 drives an aligning means for aligning sheet- like materials carried and loaded on a load-carrying part. A motor current setting circuit 82 sets a current value for the pulse motor M1. The number of sheet-like materials carried and loaded on the load-carrying part is detected by a the number of sheet materials detecting means SE11. The motor current value is switched in response to the change in the number of sheet-like materials detected. Thus, even when a means for directly detecting a loaded condition is not provided, the pulse motor can be driven by a most-suitable current value which corresponds to torque required for the motor rotary shaft, and thus there is no need for wasteful power consumption because a suitable motor-current value is set even during the period of light load.
