Abstract: A power conversion apparatus includes a semiconductor module that includes a main body containing at least one semiconductor element, power terminals projecting from the main body to be connected to a high-voltage DC power supply and high-voltage signal terminals projecting from the main body, and is configured to convert a DC power supplied from the high-voltage DC power supply to an AC power by switching operation of the semiconductor element. The power conversion apparatus further includes a low-voltage component connected to a low-voltage DC power supply and a control circuit board on which a control circuit for controlling the switching operation of the semiconductor element is formed. The control circuit board is connected with low-voltage signal terminals extending from the low-voltage component and the high-voltage signal terminals. The low-voltage and high-voltage signal terminals are solder-connected to the control circuit board.

Abstract: In a vehicle, a control apparatus controls a power converter supplying a rotary machine which can operate as a drive motor of the vehicle, and controls a cooling apparatus for circulating a coolant fluid through the rotary machine and the power converter. When a temporary condition occurs immediately after commencement of the circulation, whereby the temperatures of the coolant fluid and of switching elements in the power converter are judged to concurrently exceed respective specified temperature thresholds, the control apparatus limits the maximum power that can be supplied from the power converter to a lower value than is normally available. When the temperature of the coolant fluid is judged to no longer exceed the corresponding temperature threshold, the limiting is released.
