    摘要: A power converter capable of activating a control circuit therein without increasing a length of a wiring for conveying an external activation signal. In the power converter, a converter circuit isolates a first voltage of a first power supply, converts the first voltage into a second voltage, and outputs the second voltage to a second power supply. A first power supply connecting circuit connects the first power supply to the converter circuit in response to the activation signal. An activation circuit determines whether or not the activation signal has been received by the first power supply connecting circuit on the basis of a voltage between input terminals of the converter circuit and activates the control circuit when it is determined that the activation signal has been received by the first power supply connecting circuit.

    摘要: The control apparatus for controlling a voltage transforming apparatus having a transformer, power switching elements disposed in a primary side, and synchronous-rectifying switching elements disposed in a secondary side includes a judging circuit making a judgment as to whether or not an output current of the voltage transforming apparatus is smaller than a specified current on the basis of a primary-side current of the transformer and an inhibition circuit inhibiting the synchronous-rectifying switching elements from performing their synchronous-rectifying control operation when the judging circuit judges that the output current is smaller than the specified current. The judging circuit makes the judgment with compensating for a variation of a relationship between the primary side-current and the output current due to variation of duty ratio of the power switching elements, and variation of at least one of the DC output voltage and the DC input voltage of the voltage transforming apparatus.
