Abstract
A fail-safe static switch for controlling the supply of redundant electrical power to critical loads. A first control path has a signal analyzer configured to monitor predetermined characteristics of a power supply voltage. The signal analyzer generates a first failure signal when the characteristics of the power supply voltage monitored by the signal analyzer are not in compliance with predetermined metrics. A second control path has a first electrical circuit configured to monitor predetermined characteristics of the power supply voltage. The first electrical circuit generates a second failure signal when the characteristics of the power supply voltage monitored by the first electrical circuit are not in compliance with predetermined metrics. The fail-safe static switch further includes an output providing an electrical output signal. The electrical output signal changes state when at least one of the first failure signal and the second failure signal are generated.
