PROBLEM TO BE SOLVED: To provide a DC power supply compensation circuit that compensates a missing current included in a DC output of an AC adapter, and that has a transient phenomenon suppression function caused by variation in a load.SOLUTION: One of a series body of a first rectification element D1 and a second rectification element D2 is connected with an input terminal 1 connected with a positive electrode of an AC adapter, and the other is connected with an output terminal 3 connected with a load. A series body of a third rectification element D3 and a fourth rectification element D4 is connected in parallel with the series body of the first rectification element D1 and the second rectification element D2. One of the series bodies is connected with the input terminal 1, and the other is connected with the output terminal 3 and connected with a positive electrode (+) of a first capacitor C1. A negative electrode (-) of the capacitor C1 is connected with an output terminal 4 connected with the load, and a midpoint of the series body of the third rectification element D3 and the fourth rectification element D4 is connected with a positive electrode (+) of a second capacitor C2. A negative electrode (-) of the capacitor C2 is connected with the output terminal 4 connected with the load, and a fifth rectification element D5 is connected between the output terminals 3 and 4. |
