Abstract: A control device is applied to a power conversion system including a first power conversion device and a second power conversion device connected in parallel with a common power supply target. The control device acquires a load output including a load current or power to be supplied to the power supply target, and control operation of the first power conversion device and the second power conversion device based on at least any of a voltage parameter including any of an input voltage and an output voltage and the load output.

Abstract: A power supply device includes a transformer, a primary semiconductor component, a secondary semiconductor component, a choke coil and a circuit board. Electronic components which include the transformer, the primary semiconductor component, the secondary semiconductor component, and the choke coil, are stacked in pairs, in a normal direction of a board. One pair forms a first stacked body and another pair to forms a second stacked body. A circuit board is interposed between the one pair of electronic components which forms the first stacked body, and also between the other pair of electronic components which forms the second stacked body.

Abstract: A control device for a power supply system includes a pre-charge unit, the power supply system having a main electric storage device, a smooth capacitor, a step-up circuit, an open-close switch, a voltage source and a regulation element. The regulation element regulates a current flowing from the smooth capacitor toward the open-close switch. The voltage source is connected to a connection portion between the open-close switch and the step-up circuit, and outputs an output voltage higher than a voltage of the main electric storage device before the open-close switch is shifted from a disconnection state to a connection state. The pre-charge unit executes a pre-charge of the smooth capacitor by supplying electric power from the voltage source to the smooth capacitor before the open-close switch is shifted from the disconnection state to the connection state.
