<P>PROBLEM TO BE SOLVED: To provide a voltage converter capable of generating a highly accurate output voltage and also responding to the fluctuation of an output voltage in a short time. <P>SOLUTION: The voltage converter includes: a voltage conversion circuit (a switching circuit 10, a transformer 30, a rectifying circuit 20, and a smoothing circuit 40) for converting an input voltage Vin to a DC output voltage (an output voltage Vout); a first feedback unit (a feedback unit 50) for temporally discretely generating first feedback signals for bringing the DC output voltage close to a voltage corresponding to a voltage instruction value DVset supplied from the outside; a second feedback unit (a feedback unit 60) for temporally continuously generating second feedback signals for fixing the DC output voltage; and a control unit 70 for controlling the voltage conversion circuit on the basis of the first feedback signals and the second feedback signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
