SYSTEMS, METHODS, AND DEVICES FOR ENERGY AND POWER METERING

摘要

Disclosed herein are systems, methods, and devices for power and energy metering. Devices may include first processing logic coupled to an isolator and configured to receive a first bit stream from a first modulator via the isolator. The first bit stream may be generated by the first modulator based on a first analog signal. The first processing logic may be further configured to receive a second bit stream from a second modulator via the isolator. The second bit stream may be generated by the second modulator based on a second analog signal. The processing logic may be further configured to generate a third bit stream based on a combination of the first bit stream with the second bit stream. The devices may also include second processing logic configured to generate an output signal based on one or more values of the third bit stream. The output signal may characterize a measurement of electrical power associated with an electrical circuit.

1. A device comprising:
first processing logic coupled to an isolator and configured to receive a first bit stream from a first modulator via the isolator, the first bit stream being generated by the first modulator based on a first analog signal, the first processing logic further configured to receive a second bit stream from a second modulator via the isolator, the second bit stream being generated by the second modulator based on a second analog signal, the first processing logic further configured to generate a third bit stream based on a combination of the first bit stream with the second bit stream after the first bit stream and second bit stream have passed through the isolator; and second processing logic configured to generate an output signal based, at least in part, on one or more values of the third bit stream, the output signal characterizing a measurement of an electrical power associated with an electrical circuit, wherein the second processing logic comprises a digital filter configured to filter the third bit stream based on at least one property of a power supply.
