Abstract
A converter mounting board includes: an electronic component which is supplied an electric current; a high-frequency DC-DC converter that supplies a direct current corresponding to a fast change of the electric current of the electronic component; and a low-frequency DC-DC converter located far away from the electronic component than the high-frequency DC-DC converter and supplies a direct current corresponding to a slow change of the electric current of the electronic component.
Claims11
A converter mounting board comprising:
- an electronic component which is supplied with an electric current;
- a high-frequency DC-DC converter that supplies a first direct current corresponding to a fast change of the electric current to the electronic component;
- and
- a low-frequency DC-DC converter located farther away from the electronic component than the high-frequency DC-DC converter and that supplies a second direct current corresponding to a slow change of the electric current slower than the first direct current corresponding to the fast change of the electric current to the electronic component,
- wherein
- the high-frequency DC-DC converter and the low-frequency DC-DC converter independently output the first direct current and the second direct current to the electronic component, respectively,
- the first direct current and the second direct current output from the high-frequency DC-DC converter and the low-frequency DC-DC converter, respectively, are synthesized to be supplied to the electronic component, and
- when a frequency of a load current of the electronic component is higher than a predetermined frequency, the first direct current from the high-frequency DC-DC converter is supplied to the electronic component.
