Title:
FEEDBACK CIRCUIT
Document Type and Number:
Japanese Patent JP2019115098
Kind Code:
A
Abstract:
To provide a technology for appropriately performing feedback control in accordance with fluctuation of an output voltage.SOLUTION: A feedback circuit comprises: an input-side circuit connected to an input side of a transformer (3); and an output-side circuit connected to an output side of the transformer. The output-side circuit outputs a first voltage based on input from the input-side circuit. The input-side circuit includes: an input part (4) that performs input to the output-side circuit via the transformer; and a control part (9) that controls operation of the input part based on a feedback signal generated in accordance with the first voltage. The feedback circuit further comprises a correction part (22) for correcting the feedback signal in such a manner that the feedback signal inputted to the control part keeps linearity with respect to fluctuation of the first voltage.SELECTED DRAWING: Figure 4
