  • Patent number: 9581634
    Abstract: A power supply current monitoring apparatus is used for a load drive apparatus with two systems to drive a load. Each system includes a drive circuit connected in parallel with a battery and a relay connected between the drive circuit and a point at which power of the battery is divided between the systems. When overcurrent is detected once in one system, a repetitive monitoring process is performed. The monitoring process determines whether the overcurrent occurs by repeating a monitoring cycle. The monitoring cycle turns OFF the relay of one system and then monitors currents by turning ON the relay of one system when a predetermined cycle time elapses since the overcurrent detection. The monitoring process includes a mask procedure to stop monitoring the current in the other system. The mask procedure is performed after the relay of one system is turned OFF in each monitoring cycle.

  • Patent number: 9570902
    Abstract: A power supply current monitoring device is used for a load drive apparatus with two systems to drive a load. Each system includes a drive circuit connected in parallel with a battery, a capacitor connected between the battery and the drive circuit, and a relay connected between the drive circuit and a point at which power of the battery is divided between the systems. When overcurrent is detected once in one system, a repetitive monitoring process is performed. The monitoring process finally determines that the overcurrent actually occurs when a predetermined condition is satisfied after repeating a monitoring cycle in which an overcurrent time during which the overcurrent continues after the relay is turned ON is accumulated. The condition is satisfied when the monitoring cycle in which the overcurrent time reaches a predetermined threshold is repeated a predetermined consecutive number of times.

  • Patent number: 9460979
    Abstract: An electronic device includes a semiconductor module, a wiring substrate, a case member and a heat conducting member. The heat conducting member thermally connects predetermined portions of wiring patterns and a heat conducting pattern of the wiring substrate to a predetermined heat conduction region of a surface of the case member opposing to the wiring substrate. The predetermined heat conduction region is located further from the wiring substrate than a surface of a body portion opposing to the case member. As a result, heat can be radiated and a short can be restricted with the case member having a simple shape. The heat conducting pattern is disposed adjacent to at least one of non-terminal projecting surfaces of the body portion on a surface of the wiring substrate. As a result, an area of a heat conducting passage increases and heat radiation performance can be increased.

  • Patent number: 9431318
    Abstract: In an electronic device, a one-side heat radiation element and a two-side heat radiation element are disposed on a surface of a substrate adjacent to a heat sink. The one-side heat radiation element has a rear-side covered conductive portion and a rear-surface molded portion on the rear-side covered conductive portion adjacent to the heat sink, and radiates heat to the substrate. A surface of a rear-side exposed conductive portion of the two-side heat radiation element adjacent to the heat sink is exposed and the two-side heat radiation element radiates heat to the substrate and the heat sink. The rear-surface molded portion controls a limit position of the one-side heat radiation element toward the heat sink due to deformation of the substrate. A heat radiation gel is filled in between the rear-side exposed conductive portion and the heat sink to radiate heat from the two-side heat radiation element toward the heat sink.

  • Patent number: 8810172
    Abstract: An energization control circuit compares a target rotation direction of a motor and an actual rotation direction of a motor detected based on rotation detection sensors. If the compared rotation directions are in disagreement, the energization control circuit switches over an inverter control mode from 120-degree energization to 180-degree energization to extend an on-period of a high-side switching element of an inverter circuit to an advance phase side. Thus, the high-side switching element is turned on, when a low-side switching element of the same phase is in a turned-off state. A free-wheeling current is allowed to flow through the high-side switching element rather than through a free-wheeling diode of the high-side switching element.

  • Patent number: 7956564
    Abstract: A valve timing adjusting apparatus adjusts valve timing of at least one of intake and exhaust valves of an engine that are opened and closed by a camshaft driven by torque transmitted from a crankshaft. The apparatus includes an electric motor, a plurality of switching elements, a motor driver, and a phase adjusting mechanism. When a target rotational direction of a motor shaft of the electric motor is coincident with the actual rotational direction of the same, the motor driver continuously turns on a selected one of the switching elements for the whole of a predetermined rotation angle range of the motor shaft. When the target rotational direction is opposite to the actual rotational direction, the motor driver continuously turns on the selected switching element only for part of the rotation angle range, and continuously turns off the selected switching element for the remaining part of the rotation angle range.

  • Patent number: 6956349
    Abstract: A valve opening and closing control device of a type making use of a motor enhances driving performance of the motor and restricts heat generated by constituent elements. A bridge circuit of a motor driving circuit comprises three rows of arms comprising two switching elements connected in series to each other and two diodes connected in parallel to corresponding switching elements. The respective arms are connected in parallel to an electric source, and motor windings are connected to points of interconnection of the switching elements on the respective arms. After putting the respective switching elements of the arms in an ON state to carry an electric current to the windings, a control circuit causes the switching element in an ON state to be put as an electricity introduction stoppage element in an OFF state and causes the switching element of the same arm as that, on which the electricity introduction stoppage element is disposed, to be put in an ON state.
