<P>PROBLEM TO BE SOLVED: To provide a power supply circuit capable of effectively suppressing conductive radiation noise which may occur during load switching. <P>SOLUTION: The power supply circuit (101A) includes: a first switch (SW1) that sets connection between the power circuit and a load (M) in a conduction or shut-off state; first and second capacitors (C1, C2) connected in series between a high-potential side line (LU) and a low-potential side line (LL) of the power supply circuit; and a second switch (SW2) connected to a connection point (PM) between the first and second capacitors. The second switch connects or disconnects between the connection point (PM) and the ground. <P>COPYRIGHT: (C)2012,JPO&INPIT |
