I. Dedicated ADCs for Energy Measurement: The Cornerstone of Power Efficiency Metering and Power Quality Monitoring

1. Core Product Positioning and Technical Logic

ADI’s energy measurement ADCs are specialised analogue-to-digital conversion chips tailored for power metering, grid quality monitoring, and energy consumption control terminals. The core design eliminates the redundant features found in general-purpose ADCs, focusing instead on the specific requirements of energy metering scenarios. Key development priorities include synchronous and precise sampling, constant accuracy across a wide load range, accurate measurement of harmonics and reactive power, and high integration to simplify peripheral circuitry. These ADCs are optimised for the acquisition of power frequency AC and DC electrical signals. Beyond basic analogue-to-digital conversion, they incorporate a dedicated energy metering DSP processing core, phase compensation circuitry and anti-interference filtering modules. This enables the direct measurement of active power, reactive power, apparent power, cumulative energy, harmonic analysis, and voltage and current distortion monitoring, perfectly meeting the stringent global standards for power metering and the critical requirements of industrial energy consumption management.

In terms of technical architecture, ADI’s energy measurement ADCs predominantly employ a high-precision Σ-Δ modulation architecture, combined with a multi-channel synchronous sampling design, ensuring that the sampling timing of voltage and current signals in three-phase power systems is fully synchronised, thereby eliminating metering errors caused by phase deviation; The chips feature built-in overvoltage, overcurrent and surge protection circuits, making them suitable for complex electromagnetic interference environments in power applications, whilst also being compatible with mainstream power sensing interfaces such as current transformers, Rogowski coils and shunts, offering exceptional hardware adaptability.
