ABSTRACT:
A method for high-reliability power switching may comprise: (a) transferring possession of a token to first control logic controlling a first triode for alternating current (TRIAC), the TRIAC operably coupled to a first power source; (b) applying a voltage to a gate of the first TRIAC according to the possession of the token; (c) detecting a violation of a power source parameter; (d) transferring possession of the token to second control logic controlling a second TRIAC, the second TRIAC operably coupled to a second power source; (e) removing the voltage from the gate of the first TRIAC; and (f) applying a voltage to a gate of the second TRIAC.
