Abstract: A dual power supply transfer switch (SSATS) for switching between a first power supply (S1) and a second power supply (S2) to supply power to a load is provided, includes: a solid-state switch (SS); a mechanical switch (CTR); and a compensation power module (AUX). In the case that the S1 fails in supplying power to the load, the AUX uses the S2 to supply power to the load, and the output current of the S1 is reduced. After satisfying the turn off condition for the SS, the SS turns off the S1, the CTR turns off the S1 and turns on the S2. After the S2 is adjusted to synchronize with the phase of the output current of the S1, the SS turns on the S2 and the AUX stops outputting current. The SSATS provides advantages such as fast transfer, zero interruption, and short voltage sag time.
