A SWITCHING ARRANGEMENT FOR SWITCHING BETWEEN TWO INPUTS, EQUIPMENT, SYSTEM AND A METHOD
Document Type and Number:
WIPO Patent Application WO/2018/113704
Kind Code:
A1
Abstract:
A switching arrangement for switching between two inputs is disclosed herein. The switching arrangement include a first semiconductor switch, a first mechanical switch, a second mechanical switch, the second mechanical switch being connectable to the main or backup input, and a controller being coupled to the first semiconductor switch, the first mechanical switch and the second mechanical switch; wherein the controller is configured to generate control drive signals for the first semiconductor switch, the first mechanical switch and the second mechanical switch, the control drive signals being configured to switch off the first mechanical switch at zero voltage, and switch the second mechanical switch from the main input to the backup input or from the backup input to the main input at zero current, wherein the second mechanical switch is switched to the backup input or the main input while the first mechanical switch is off.
