  • Patent number: 10757842
    Abstract: An electrical power conversion apparatus is provided which includes a semiconductor module and a plurality of cooling pipes. Each of the cooling pipes has an electrical conductivity and a cooling medium flow path formed therein. Each of the cooling pipes is equipped with a flow path extension forming portion which protrudes above a module body in at least one of height-wise directions and in which a portion of the cooling medium flow path is formed. The flow path extension forming portion overlaps at least either of the power terminals or the control terminals in a stacking direction of the cooling pipes. This enhances the efficiency in decreasing the inductance of the power terminals and/or the control terminals, improves the productivity of the electrical power conversion apparatus, and enables the size of the electrical power conversion apparatus to be reduced.

  • Publication number: 20200088124
    Abstract: An ECU opens a valve element to inject fuel in conjunction with energization of a fuel injection valve provided for an engine. The ECU includes an injection control unit, a characteristic acquisition unit, and a fuel injection correction unit. The injection control unit implements a partial-lift injection during which the valve element does not reach a full-lift position to open the fuel injection valve by an energization time. The characteristic acquisition unit acquires an actual lifting behavior of the valve element as an actual lift characteristic when the partial-lift injection is implemented. The fuel injection correction unit compares the actual lift characteristic acquired by the characteristic acquisition unit with a predetermined reference characteristic and corrects a fuel injection quantity in the partial-lift injection based on a result of the comparison.
