Power disturbance detection circuit and method |
摘要 |
A method and apparatus are disclosed for detecting disturbances in an alternating current (AC) supply. A method includes a step of indicating a relationship between supplied AC voltage and a threshold voltage for at least a portion of each cycle of the supplied AC voltage. A circuit for detecting disturbances in supplied alternating current (AC) is provided. The circuit includes a threshold detector coupled to a source of supplied AC. The threshold detector provides a signal indicating a relationship of the supplied AC levels to a threshold level for at least a portion of each cycle of the supplied AC.
