摘要： A power black-out sensing system includes: a primary power source providing an alternating current (AC) power using three phase wires and a neutral wire; a secondary power source; a sensing block comprising one or more sensing elements; and a rectifier configured to rectify the AC power from the primary power source and providing a rectified power to the sensing block voltage detector. Two wires of the three phases wires and the neutral wire of the primary power source are connected to rectifier, and a first wire of the two wires is connected to the rectifier via a switch and a second wire of the two wires is directly connected to the rectifier. The sensing block detects a phantom voltage and provides an output signal corresponding the secondary power source during a blackout period.

摘要： A calibration amplifier includes: a plurality of transistors and a variable resistor configured to change in response to clock pulses. During a calibration cycle, one of the plurality of transistors switches on in each calibration step based on a plurality of enable signals, and a gain of the calibration amplifier changes until an output voltage of the calibration amplifier exceeds a reference voltage and is set to a calibrated gain. The calibration amplifier outputs the output voltage by amplifying an input voltage using the calibrated gain.

摘要： A power blackout sensing system includes: a voltage regulator configured to receive one of three phase wires and a neutral wire of a primary power source that provides an alternating current (AC) power; a sensing block configured to receive the neutral wire of the primary power source and comprising a coupled inductor device and a voltage sense amplifier; and a secondary power source. The voltage regulator is coupled to a switch and generates a direct current (DC) voltage signal. The coupled inductor device of the sensing block comprises a pull-down resistor, wherein the coupled inductor device is configured to convert a voltage signal of the neutral wire to a 180-degree phase-shifted voltage signal of the neutral wire and generate a reference voltage signal using the pull-down resistor. The voltage sense amplifier is configured to amplify a voltage gap between the 180-degree phase-shifted voltage signal of the neutral wire and the reference voltage signal. The sensing block detects a phantom voltage on the one of three phase wires and provides an output signal corresponding the secondary power source during a blackout period.
