Abstract
A dual power supply transfer switch (SSATS) for switching between a first power supply (S) and a second power supply (S) 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 Sfails in supplying power to the load, the AUX uses the Sto supply power to the load, and the output current of the Sis reduced. After satisfying the turn off condition for the SS, the SS turns off the S, the CTR turns off the Sand turns on the S. After the Sis adjusted to synchronize with the phase of the output current of the S, the SS turns on the Sand the AUX stops outputting current. The SSATS provides advantages such as fast transfer, zero interruption, and short voltage sag time.
