摘要： A DC matrix power switch structure electrically connects m DC power modules to n charge dispensers for charging electric vehicles. The matrix includes an input structure having m conducting input busbar pairs and an output structure having n conducting output busbar pairs. A first busbar of m input busbar pairs is connected to a positive voltage terminal and a second busbar of m input busbar pairs is connected to a negative voltage terminal of each of m DC power modules. A third busbar of n output busbar pairs is connected to a positive voltage terminal and a fourth busbar of n output busbar pairs is connected to a negative voltage terminal of each of n charge dispensers. The combination produces two times m×n busbar crossing points. A power switch, when activated, electrically connects to the associated busbar at the busbar crossing point.

摘要： A DC matrix power switch structure mechanically and electrically connects m DC power modules to n charge dispensers for charging electric vehicles. The matrix includes an input structure having m conducting input busbar pairs and an output structure having n conducting output busbar pairs. A first busbar of n output busbar pairs is connected to a positive voltage terminal and a second busbar of n output busbar pairs is connected to a negative voltage terminal of each of n charge dispensers, producing two times m×n busbar crossing points. A power switch is mechanically mounted to a cross point or is moved to a crossing point and, when activated, connects to the associated busbar at the busbar crossing point providing power to the appropriate charge dispenser. A power switch includes one or more actuators to connect an input busbar to an output busbar with a flexible conductor.
