Description: This paper presents a new FPGA-based harmonic detection system design. In the scheme, using the FFT for fast FPGA computing, digital phase-locked loop to synchronize the measured signal to reduce the non-synchronous sampling error arising from implementation of the design and implementation are given. Digital PLL and FFT algorithm design and implementation using VHDL language, the program can improve the accuracy of harmonic analysis and response speed, and greatly streamline the hardware circuit, the system is very easy to upgrade.
