Title: High-frequency direct current bulk capacitors with interleaved busbar packages

Abstract

Presented are electrical capacitors with interleaved busbar architectures, methods for making/operating such capacitors, and electric-drive vehicles equipped with such capacitors. A bulk capacitor includes multiple capacitor devices disposed within an outer housing and operable to modify electric current transmitted between a power source and an electrical load. An interleaved busbar package is interposed between the capacitor devices and outer housing. The interleaved busbar package includes a first busbar plate that electrically connects to first terminals of the capacitor devices and defines a busbar pocket. A second busbar plate is seated within the busbar pocket and electrically connects to second terminals of the capacitor devices. The second busbar plate includes a capacitor basin that seats therein the capacitor devices. An isolator sheet is interleaved between and electrically insulates the first and second busbar plates. The capacitor devices and interleaved busbar package may be partially submerged in an epoxy endfill composition.
