  • Patent number: 10903649
    Abstract: A static transfer switch is provided for supplying power to a load alternately from two different power sources. Switching between the two power sources may occur within a fraction of one electrical cycle. In response to sensing degraded performance in the power source supplying the load, a gate signal is turned off to a first switch coupled between the power source and the load. A third switch coupled between an energy storage and the first switch is also closed to release a current to the input or output of the first switch The current forces a drop in current conducted through the first switch and causes the first switch to open and stop conducting current. A second switch coupled between the alternate power source and the load is then closed to supply power to the load from the alternate power source.
