Analysis of Harmonic Detection of APF&SVG
This paper reviews the harmonic current detection algorithm of APF&SVG. And the new different research of each detection method is introduced. The advantage and disadvantage of each methods is also analyzed. It has provided some references to the electric current detection algorithm choice for the design of the APF and SVG.
In this paper we study the multivariate ANOVA decomposition for $1$-periodic functions on the torus. In particular we use the integral projection operator that leads to the classical ANOVA decomposition. Relationships between the Fourier coefficients of the function and its ANOVA terms lead to special frequency index sets and give an understanding of the decomposition working in the frequency domain. Moreover, we consider the truncated ANOVA decomposition and provide error bounds for approximation in $\mathrm{L}_\infty$ and $\mathrm{L}_2$. We present an approximation method based on the truncated decomposition with regard to a superposition dimension $d_s$.
