Swift F., Kamberis A. A New Walsh Domain Technique of Harmonic Elimination and Voltage Control in Pulse-Width Modulated Inverters

IEEE Transaction on Power Electronics, vol. 8, No. 2, April 1993, pp. 170-185.
A new method is presented or selective harmonic elimination in pulse-width (PWM) inverter waveforms by the novel use of Walsh functions. The Walsh operational matrix of pulse-width modulation (WOM-PWM) is introduced as a means of obtaining the Walsh spectral equations of PWM waveforms. The slope and intercept Fourier operational matrices of pulse-width modulation (SFOM-PWM and IFOM-PWM) are also introduced as a means of obtaining Fourier spectral equations of PWM waveforms.

25 страниц. Статья по применению продукции Fairchild Semiconductor. Application Note AN-3008. RC networks are used to control voltage transients that could falsely turn-on a thyristor. These networks are called snubbers. The simple snubber consists of a series resistor and capacitor placed around the thyristor. These components along with the load inductance form a series CRL circuit. Snubber theory follows from the solution of the circuit’s di...

11 страниц IEEE Transactions on Power Electronics, Vol. 16, No. 4, July 2001 Various aspects of averaged modeling of hardswitching pulse-width modulated (PWM) converters operating in the discontinuous conduction mode (DCM) are studied. A more streamlined modeling procedure is proposed which serves as a general framework for comparing different models. A duty ratio constraint that defines the diode conduction interval is identified to be the key t...
