Claim 9:
10. The static transfer switch of claim 8, wherein when currents are conducted through the first and second silicon controlled rectifier elements before the first and second bypass electric circuits are closed, currents of the positive and negative output terminals of the AC-DC converter are output through the first paths, and
wherein when the first and second bypass electric circuits are closed while the currents are conducted through the first and second silicon controlled rectifier elements, the currents of the positive and negative output terminals of the AC-DC converter are output through both the first paths and the second paths, and when the first and second silicon controlled rectifier elements are turned off while the first and second bypass electric circuits are closed, the currents of the positive and negative output terminals of the AC-DC converter are output only through the second paths.
