Description:    This design uses ATMEL Corporation ATmega32L MCU to complete a power quality detection system. Voltage signal through a transformer-isolated buck, lower amplitude AC signal through another operational amplifier adders into a DC signal of A/D conversion circuit for conversion. After the MCU internal timer every 1/3200 second voltage signal is sampled once with chip comes with 10-bit precision A/D converter for sampling a voltage signal per cycle of 64 points, the FFT computation, FFT calculation uploaded to the host process to take up table method further improve processing speed, analyze the content of less than 21 times each harmonic, and calculate the RMS voltage signal (RMS), harmonic analysis results via RS-232 serial interface storage and display machine.
