Introduction to Power Electronics Introduction to Power Electronics

Fast Fourier Transform ( FFT )

The DFT can be reduced from exponential time with the Fast Fourier Transform algorithm. Fast Fourier Transform (FFT) One wonders if the DFT can be computed faster: Does another computational procedure an algorithm exist that can compute the same quantity, but more e ciently. We could seek methods that reduce the constant of proportionality, but do not change the DFT's complexity O ( N ) . Here,...

Interactive Power Electronics Tool for Undergraduate Laboratories and Research Purposes

This research proposes the use of hardware emulation for inverter plants for the first time. This results in a new low cost, safe and robust solution for teaching control strategies for power electronics inverter circuits, composed of a digital controller (DSP or FPGA) connected to the inverter “hardware emulation circuit”. The inverter dynamical behavior is emulated by cheap operational amplif...

A wavelet approach to fast approximation of steady-state waveforms of power electronics circuits

Waveforms arising from power electronics circuits often contain slowly changing segments with highfrequency details concentrated near the switching instants. Such a feature is consistent with the localization property of wavelets which are known in the signal processing literature to be highly suitable for describing fast changing edges embedded in slowly varying backgrounds. This paper conside...

Fast Controller for a Unity-Power-Factor PWM Rectifier - Power Electronics, IEEE Transactions on

This paper presents an analog implementation of a fast controller for a unity-power-factor (UPF) PWM rectifier. The best settling times of many popular controllers for this type of converter are on the order of a few line cycles, corresponding to bandwidths under 20 Hz [l]. The fast controller demonstrated in this paper can exercise control action at a rate comparable to the switching frequency...
