Title (EN) INVERTER DEVICE AND ELECTRIC POWER TOOL
(FR) DISPOSITIF D'ONDULEUR ET OUTIL DE PUISSANCE ÉLECTRIQUE
Abstract: front page image
(EN)An inverter device includes: an inverter circuit configured to perform ON/OFF operations with a preset duty cycle to convert a DC power into an AC power and output the AC power to an AC motor; and a controller configured to change a duty cycle of the ON/OFF operations.
(FR)L'invention porte sur un dispositif d'onduleur, qui comprend: un circuit d'onduleur configuré de façon à effectuer des opérations de MARCHE/ARRET avec un rapport cyclique prédéfini pour convertir une alimentation en courant continu en une alimentation en courant alternatif et délivrer en sortie l' alimentation en courant alternatif à un moteur en courant alternatif; et un dispositif de commande configuré de façon à changer un rapport cyclique des opérations de MARCHE/ARRET.
