The rapid three-phase harmonic analyzer based on high-precision energy metering chip was de-signed.The analyzer employs an embedded structure,adopts SOC platform technology and takes STM32 proces-sor as the core,as well as carries ATT7022D dedicated energy metering IC through address/data bus.The ana-lyzer uses ADC caching function to realize the data’ s rapid acquisition,and the STM32 processor with in-built dedicated FFT algorithm can implement harmonic analysis;and the Lagrange cubic interpolation algorithm em-ployed can correct the spectral leakage and picket fence effect incurred.Application experiments prove this an-alyzer’ s high acquisition accuracy,processing speed and high reliability.
