Neutral switching high speed AC transfer switch

摘要

A hybrid neutral transfer switch in an electrical system to transfer a load between multiple AC power sources is provided. The hybrid neutral transfer switch includes a neutral gate controlled device connected to a neutral input of each of the multiple power sources and a mechanical transfer switch that switches between the neutral input of each of the power sources. During the transfer of power from one power source to another power source, the neutral gate controlled devices are activated and/or deactivated in conjunction with the switching of the mechanical transfer switch from one neutral input to another neutral input.
