Classification: CPC H  Y | IPC H

Claim 0:
1. A DC/DC converter, comprising:
a first end comprising a high-voltage positive terminal and a high-voltage negative terminal;
a second end comprising a low-voltage positive terminal and a low-voltage negative terminal, wherein the low-voltage negative terminal is electrically connected with the high-voltage negative terminal;
a first capacitor, wherein a first terminal of the first capacitor is electrically connected with the high-voltage positive terminal, and a second terminal of the first capacitor is electrically connected with the low-voltage positive terminal;
a power conversion circuit, disposed between the first end and the second end and providing a conversion between a high voltage at the first end and a low voltage at the second end, wherein the power conversion circuit comprises at least one switch and at least one magnetic assembly; and
a second capacitor;
wherein a first terminal of the second capacitor is electrically connected with the low-voltage positive terminal, a second terminal of the second capacitor is electrically connected with the low-voltage negative terminal, and second capacitor is configured to filter a voltage ripple at the second end,
wherein the first capacitor and the second capacitor are electrically connected in series and configured to filter a voltage ripple at the first end.
