Load break DC power disconnect |
摘要 |
An embodiment of the invention is a DC power disconnect having a first mechanical switch for coupling a DC power module to a first rail of a DC bus and a second mechanical switch for coupling the DC power module to a second rail of the DC bus. A first solid-state switch couples the DC power module to the first rail of the DC bus and is positioned in parallel with the first mechanical switch. A second solid-state switch couples the DC power module to the second rail of the DC bus and is positioned in parallel with the second mechanical switch. A controller initiates closing the first solid-state switch and the second solid-state switch prior to changing state of the first mechanical switch and the second mechanical switch.
