Abstract
Dispositif électronique, p. ex. un radiotéléphone, connectable à une source d'alimentation à niveau variable (106). Comprend une source d'alimentation rechargeable (188) au moyen de l'alimentation de fonctionnement à niveau variable (106). Un régulateur à courant de charge constante (168) permet de convertir l'alimentation de fonctionnement à tension constante en une alimentation de fonctionnement à courant constant destinée à être appliquée à la source d'alimentation rechargeable (188) afin de la (188) recharger. Le régulateur (168) est composé d'un montage en série de diodes (176) et d'une paire de résistances (172). Selon un autre aspect de l'invention, lorsque la source d'alimentation rechargeable est entièrement rechargée, l'application de l'alimentation de fonctionnement peut être réduite par commutation (206).
