Title (EN) METHOD AND APPARATUS FOR PROVIDING PULSE WIDTH MODULATION
(FR) PROCEDE ET APPAREIL POUR ASSURER LA MODULATION D'IMPULSIONS EN DUREE
Abstract: front page image
(EN)A pulse width modulation scheme allows the creation of a unipolar pulse width modulated output signal. Two switching circuits (104, 204), preferably different legs of an inverter circuit, can operate to not only modulate an input voltage but also to reverse the polarity of the PWM output signal. Both switching circuits can be configured to accomplish both features, thus the switching load is spread out across all four switches.
(FR)La présente invention concerne un schéma de modulation d'impulsions en durée permettant la génération d'un signal unipolaire de sortie d'une impulsion modulée en durée. Deux circuits de commutation (102, 104), de préférence différentes branches d'un circuit d'inversion, peuvent fonctionner non seulement en vue de moduler une tension d'entrée mais également d'inverser la polarité du signal en sortie de la modulation d'impulsions en durée. Les deux circuits de commutation peuvent présenter une configuration leur permettant d'effectuer les deux opérations, permettant ainsi d'étaler la charge de commutation sur tous les quatre commutateurs.
