Abstract
A power supply device converts power supplied from a power source to power to be supplied to a load and supplies the converted power to the load from an output terminal. The power supply device includes a capacitor that includes a case, a first terminal exposed outside the case, and a second terminal exposed outside the case. The first terminal is fixed to a busbar. The busbar electrically connects the first terminal to the output terminal of the power supply device. The second terminal is fixed to an electrically conductive support that receives a reference potential.
Claims21
A power supply device for converting power supplied from a power source to power to be supplied to a load and supplying the converted power to the load from an output terminal, the power supply device comprising:
- a power converter to convert the power supplied from the power source to the power to be supplied to the load and to output the converted power to the output terminal;
- a capacitor including a dielectric, two electrodes opposing each other with the dielectric in between, a case accommodating the dielectric and the two electrodes, a first terminal electrically connected to one of the two electrodes and exposed outside the case, and a second terminal electrically connected to the other one of the two electrodes and exposed outside the case, the capacitor being located in a circuit between the power converter and the output terminal;
- a busbar to which the first terminal is fixed, the busbar electrically connecting the first terminal to the output terminal;
- and
- an electrically conductive support to which the second terminal is fixed, the electrically conductive support being configured to receive a reference potential.
4-12. (canceled)
