Title (EN) DISCHARGING CIRCUIT FOR RECTIFYING POWER SOURCE
(FR) CIRCUIT DE DECHARGE POUR UNE SOURCE DE COURANT DE REDRESSEMENT
Abstract: front page image
(EN)A discharging circuit for a rectifying power source used as a DC power source for driving a motor, in which the voltage of a time constant circuit (22, 23) drops abruptly when the AC power source is interrupted and the load is disconnected, the voltage across a diode (25) rises, operating a Schmitt trigger circuit (24) to make a circuit of a transistor (27) and a resistor (26) conductive and discharge the smoothing capacitor (28), thereby reducing the heat dissipation of the resistor and eliminating a danger in the safety of the circuit due to a delay in discharging the capacitor.
(FR)Un circuit de decharge pour une source de courant de redressement utilise une source de courant continu pour entrainer un moteur, dans lequel la tension d'un circuit (22, 23) a constante de temps baisse brusquement lorsque la source de courant alternatif est interrompue et la charge est deconnectee, la tension aux bornes d'une diode (25) augmente, actionnant un circuit (24) a gachette de Schmitt de maniere a rendre conducteur un circuit compose d'un transistor (27) et d'une resistance (26) et decharger le condensateur (28) d'egalisation, en reduisant ainsi la dissipation de chaleur de la resistance et en eliminant le danger que represente un retard dans la decharge du condensateur.
