Estimation Method for Fundamental Components of Single Phase Signals using Quadrature Signal Generator with the First Order Low Pass Filter

Abstract

This paper proposes a new quadrature signal generator and an estimation method for fundamental components of single phase signals with the generator. In the proposed method, the quadrature signal is generated with the difference of input signal and the first order LPF output. The effectiveness of the estimation method for the fundamental components with the quadrature signal is confirmed by the simulation results.
