Title (EN) PULSE WIDTH MODULATION DEAD TIME COMPENSATION METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE COMPENSATION DE TEMPS MORT DE MODULATION PAR LARGEUR D'IMPULSION
Abstract: front page image
(EN)Dead time compensated complementary pulse width modulation (PWM) signals (PWMH, PWML) are derived from a PWM generator by first applying time period compensation to the PWM generator signal (450) based upon the direction of current flow in an inductive load (correction control: 440) being controlled by the PWM generator. Dead time is then applied to the compensated PWM generator signal (462) for producing complementary dead time compensated PWM signals (PWMH, PWML) for controlling power switching circuits driving the inductive load.
(FR)Des signaux de modulation par largeur d'impulsion (PWM) complémentaires à temps mort compensés (PWMH, PWML) sont dérivés à partir d'un générateur PWM tout d'abord par application d'une compensation temporelle au signal de générateur PWM (450), sur la base de la direction de la circulation de courant dans une charge inductive (commande de correction : 440) qui est commandée par le générateur PWM. Un temps mort est ensuite appliqué au signal de générateur PWM compensé (462) pour produire des signaux PWM à temps mort compensés complémentaires (PWMH, PWML) pour commander des circuits de commutation de puissance commandant la charge inductive.
