Inverter Components and Functions

5. Insulator, Isolates TPaks to prevent electrical arcing or shorting to other parts.
7. Busbar, Distributes even current throughout the TPaks.
10. Busbar, Receiving station on which power is concentrated for distribution out of the Inverter to the stator housing.
13. stores potential energy in an electric field.
14. Ports, Attached to a hose line will send coolant through the case heat sink that cools the TPaks.
16. Converts DC to AC energy for power variability
17. Pad, Used for protection of the resistors on the PCBA area that it’s attached to.
18. Central in process management: They are accessed and/or modified by most OS utilities.

1. Cover, Allows coolant to flow through the coolant ports which cools the heat sink to keep the TPaks at optimal temperature.
2. Clip, used to lock the ASY, Logic Connector in place and helps support the PCBA board to prevent flex when connecting the vehicles Logic Connection.
3. Paste, 80% silver and 20% solvent. Used to attach the TPaks onto the case pedestals.
4. Connector, used to house the 30 pin connection to the PCBA, with gasket included.
6. Discharge, The release of built-up electricity that is released when 2 objects of opposite charge interact.
8. Semiconductor switches used to create a high and low phase. This creates a 3 phase alternating current.
9. Busbar, Protects the TPaks and helps control electrical flow around the inverter.
11. Header, Main input into the Inverter. It transfers the high voltage current from the battery pack and through the Inverter to be distributed to the drive unit.
12. Made from cast aluminum with silver coated pedestals where semiconductors (TPaks) will be applied and sintered.
15. Ensures that external fluid does not contact the internal electronics of the inverter through the case seal.
