Abstract
An inverter drive assembly includes a first bus bar having a plurality of bushings, including at least a first bushing and a second bushing, the first bus bar being configured to receive at least one DC link capacitor of the inverter drive assembly via the second bushing, a second bus bar electrically connected to the first bus bar at the first bushing, and an inverter electrically connected to the second bus bar, the inverter being configured to receive electrical current through the second bus bar, wherein a height of the first bushing defines an air gap of approximately 5 millimeters between the first bus bar and the second bus bar.
Claims19
An inverter drive assembly, comprising:
- a first bus bar having a plurality of bushings, including at least a first bushing and a second bushing, the first bus bar being configured to receive at least one DC link capacitor of the inverter drive assembly via the second bushing;
- a second bus bar electrically connected to the first bus bar at the first bushing;
- and
- an inverter electrically connected to the second bus bar, the inverter being configured to receive electrical current through the second bus bar;
- wherein a height of the first bushing defines an air gap of approximately 5 millimeters between the first bus bar and the second bus bar.
A bus bar for an inverter drive assembly of a vehicle, comprising:
- a first layer;
- a second layer laminated to the first layer;
- at least one first bushing configured to receive a capacitor;
- and
- at least one second bushing configured to receive an inverter bus bar connected to an inverter of the inverter drive assembly;
- wherein the at least one second bushing is approximately 5 millimeters in height;
- and
- wherein the first layer and the second layer substantially entirely overlap.
A method comprising:
- providing a first bus bar;
- and
- connecting a second bus bar having a conductor to the first bus bar to define an air gap between the first bus bar and the second bus bar;
- wherein the air gap is substantially 5 millimeters.
