20150155762 | SEMICONDUCTOR MODULE AND DRIVER DEVICE - A semiconductor module includes a switching element, a molded body, and a motor terminal. The molded body having the switching element disposed therein. The motor terminal has a base portion and a connection portion having an insertion hole into which a motor wire is inserted and connected with the winding wire. The connection portion has a cutaway region that defines a slot. The winding wire of the motor and the semiconductor module are connected via the motor wire and the motor terminal, thereby reducing the number of components used for such connection compared with a connection that uses a connector, and achieving a volume reduction of the semiconductor module and a driver device using the same. | 06-04-2015 |
20150155763 | DRIVER DEVICE - A driver device has a semiconductor module in which a motor terminal extends from a molded body and is connected to a motor wire. A heat sink of the driver device has a module mounting surface, which extends axially outward from an axial end of the motor section, on which the semiconductor module is fastened. The motor terminal includes a base region on a molded body side of a bend location and an extension region on a tip side of the bend location. The extension region has a connection portion on which an insertion hole receives the motor wire. A terminal angle between the extension region and a perpendicular line perpendicular to the motor wire is greater than zero degree. As such, the volume of the driver device is reduced. | 06-04-2015 |

20090256509 | MOTOR CONTROL DEVICE - A motor control device has a three-phase bridge circuit, a driving circuit, and a microcomputer. The three-phase bridge circuit has three pairs of MOSFETs for U, V, and W phases of a three-phase AC motor as a control target. The microcomputer has a dead time set value storage unit and a PWM signal generation unit. The PWM signal generation unit generates a PWM signal with a dead time including a response characteristics of the pair of MOSFETs for each of U, V, and W phases of the AC motor based on a three-phase voltage instruction value supplied from an outside device and the dead time set value stored in the dead time set value storage unit. The PWM signal generation unit outputs the PWM signal for each phase to the driving circuit. This independently adjusts the dead time for the MOSFETs for each phase. | 10-15-2009 |
