Abstract

In order to measure the peak value of the sinusoidal wave more conveniently, we did a full-wave rectification to the sinusoidal wave, then analyzed its frequency spectrum by using Fourier analysis. By researching the relationship between the DC component in the spectrum and the peak voltage, this paper provided a voltage peak value detect circuit based on the Fourier analysis. The detect circuit is including precision full wave rectifier circuit, second-order RC filter circuit and an ADC converter. Also this paper gives a technique based on the regression analysis in order to reduce the error due to the nonlinear characteristics and the manufacture errors between the real components. By doing the regression analysis of the raw data, which using MATLAB, the circuit will allow measuring error within 2%.
