Abstract
An on-board charger includes input ports, output ports, an AC-DC converter, an isolated DC-DC converter, a first filter, and a second filter. The first filter is connected to the input ports. The first filter includes a first common mode choke coil, a first across-the-line capacitor, and first line bypass capacitors. The second filter is connected between the isolated DC-DC converter and each of the output ports. The second filter includes a second common mode choke coil and second line bypass capacitors.
Claims20
A power supply device comprising:
- input ports respectively connected to two alternating current lines to which alternating current power is input;
- output ports respectively connected to two direct current lines from which direct current power is output;
- a first filter connected to the input ports;
- an AC-DC converter that is connected to the first filter and that is configured to convert the alternating current power to the direct current power;
- an isolated DC-DC converter that is connected to the AC-DC converter and that is configured to convert a direct current voltage to a direct current voltage having a predetermined voltage value;
- and
- a second filter connected between the isolated DC-DC converter and each of the output ports,
- wherein
- the first filter includes at least one first common mode choke coil connected at halfway points of the two alternating current lines, at least one first across-the-line capacitor connected between the two alternating current lines, and at least one first line bypass capacitor connected between each of the two alternating current lines and a ground, and
- the second filter includes at least one second common mode choke coil and a second line bypass capacitor, the second common mode choke coil being connected at halfway points of the two direct current lines, the second line bypass capacitor being connected between each of the two direct current lines and a ground.
