PASSIVE ELEMENT-THYRISTOR PARALLEL CONNECTION FOR MITIGATING INRUSH CURRENT IN STATIC TRANSFER SWITCH

Disclosed herein is a static transfer switch and methods of operating the same. The static transfer switch includes a first switch between a first voltage source and a load, and a second switch between a second voltage source and the load. The first switch and the second switch are configured to alternate power to the load between the first voltage source or the second voltage source. The static transfer switch also includes a first parallel circuit branch coupled in parallel to the first switch, the first parallel circuit branch comprising a first passive element and a first auxiliary switch.
