Abstract
Voltage conversion systems including double-sided (direct current) DC-link capacitor systems are provided. The voltage conversion system includes a voltage conversion circuit and a double-sided DC-link capacitor system electrically coupled to the voltage conversion circuit. The double-sided DC-link capacitor system includes a busbar system, a first capacitor unit disposed on a first side of the busbar system and electrically coupled to the busbar system, and a second capacitor unit disposed on a second side of the busbar system and electrically coupled to the busbar system. The second side of the busbar system is opposite the first side of the busbar system. A current flow through the busbar system flows to the first capacitor unit in a first current flow direction and to the second capacitor unit in a second current flow direction. The second current flow direction is opposite the first current flow direction.
