Abstract: <P>PROBLEM TO BE SOLVED: To provide a power supply device wherein constant output voltage can be maintained through a simple circuit configuration even if input voltage varies over a wide range and the harmonic component of input current is at the low level.  <P>SOLUTION: The power supply device controls turn-on/off of the switching element Q<SB>1</SB>of a chopper circuit which is fed with undulating voltage Vi, or the output of a rectifier RE which full-wave-rectifies alternating-current power supply AC. The power supply device carries out this control based on first detection voltage V<SB>1</SB>in proportion to the undulating voltage Vi, second detection voltage V<SB>2</SB>in proportion to output voltage Vo, third detection voltage V<SB>3</SB>in proportion to exciting current to the switching element Q<SB>1</SB>, and fourth detection voltage e<SB>2</SB>corresponding to current passed through an inductor CH. The power supply device is provided with a voltage regulation circuit 4. As the instantaneous value of undulating voltage Vi increases, the voltage regulation circuit 4 regulates voltage so that the ratio of the first detection voltage V<SB>1</SB>to the instantaneous value of undulating voltage Vi is reduced.  <P>COPYRIGHT: (C)2004,JPO
