—The discrete Fourier transform (DFT) is still a widely used tool for analyzing and measuring both stationary and transient signals in power system harmonics. However, the misappli-cations of the DFT can lead to incorrect results caused by some problems such as an aliasing effect, spectral leakage, and picket-fence effect. A strategy of recursive(More)
—General power system supply only provides a fixed voltage and frequency, and its the inverter is mostly used to control AC motor speed with different frequencies. However, it normally requires a rectified DC into AC for the frequency variation. In this study, a digital signal processing technology is developed to generate a Sine Wave Pulse Width Modulation(More)
