HYBRID FAST TRANSFER SWITCH AND METHOD FOR FAST SWITCHING BETWEEN POWER SUPPLIES BY USING SAME

WIPO Patent Application WO/2024/002144

A1

Provided are a hybrid fast transfer switch and a method for fast switching between power supplies by using same. The hybrid fast transfer switch comprises: a mechanical switch, comprising a first static contact, a second static contact and a moving contact, wherein the first static contact is connected to a first power supply, the second static contact is connected to a second power supply, and the moving contact is connected to a load; a first transfer branch connected between the first power supply and the load; a first energy absorption branch connected between the first power supply and the load; a second transfer branch connected between the second power supply and the load; and a second energy absorption branch connected between the second power supply and the load. According to embodiments of the present invention, the hybrid fast transfer switch can realize fast switching between two power supplies under large current, reduces loss under a normal working condition, and has better overload and short-circuit withstand capabilities.
