Title (EN) CONTROLLER FOR SWITCH-MODE CIRCUITRY
(FR) ORGANE DE COMMANDE POUR CIRCUIT EN MODE DE COMMUTATION
Abstract: front page image
(EN)A dual mode controller is used to control switching circuitry by operating in either a voltage mode or a current mode on the basis of an output signal of the switching circuitry. The dual mode controller includes a voltage mode controller, a current mode controller, and a control circuit to control one of the voltage mode controller or current mode controller in response to the output signal of the switching circuit. The voltage mode controller and current mode controller can generate first and second pulse width modulated signals. The control circuit, in response to the output signal from the switching circuitry, operates the voltage mode controller and current mode controllers to provide one of the first pulse width modulated signal and the second pulse width modulated signal to an input of the switching circuitry.
(FR)L'invention concerne un organe de commande double mode destiné à commander un circuit de commutation en mode tension ou en mode courant selon un signal de sortie du circuit de commutation. L'organe de commande double mode comprend un organe de commande de mode tension, un organe de commande de mode courant et un circuit de commande pour commander l'organe de commande de mode tension ou l'organe de commande de mode courant en réponse au signal de sortie du circuit de commutation. Les organes de commande en mode tension et en mode courant sont capables de produire un premier signal et un deuxième signal modulés en durée. Le circuit de commande, en réponse au signal de sortie du circuit de commutation, actionne l'organe de commande en mode tension et des organes de commande en mode courant pour appliquer le premier ou le deuxième signal modulés en durée à une entrée du circuit de commutation.
