絶縁型電源装置、給電システム
Document Type and Number:
Japanese Patent JP7054350
Kind Code:
B2
Abstract:
To provide an isolated power supply device capable of suppressing variations in an output voltage of a transformer due to fluctuations in a load current, and a power supply system including the insulated power supply device.SOLUTION: An insulated power supply device 100 comprises: a first transformer 60 in which one first input winding 61 and a plurality of first to fourth output windings 62 to 65 are magnetically coupled by a common core C1, and a second transformer 67 in which a second input winding 68 and a second output winding 69 are magnetically coupled. The first transformer 60 has a feedback winding 66 magnetically coupled to the input winding 61 and the output windings 62 to 65. A power supply IC 52 operates a control switch 80 to control the output voltage of the output side winding of the first transformer 60 on the basis of the voltage generated in the feedback winding 66.SELECTED DRAWING: Figure 2
