  • Circuit and method for detecting zero-crossings and brownout conditions on a single phase or multi-phase system
    Patent number: 9581626
    Abstract: A circuit configuration detects zero-crossings and/or a brownout condition. The circuit configuration contains a zero-crossing detection circuit, a brownout detection circuit, an isolation and digitization circuit connected to the zero-crossing detection circuit and the brownout detection circuit, and a filtering circuit connected to the isolation and digitization circuit. The single circuit configuration can be used for detecting zero-crossings of single-phase and multi-phase systems as well as ascertaining a brownout condition of either the single-phase or the multi-phase systems.
