Title
(EN) RESISTIVE MIRROR BASED CONTROLLABLE CONSTANT POWER GENERATOR
(FR) GÉNÉRATEUR DE PUISSANCE CONSTANTE RÉGLABLE À BASE DE MIROIR RÉSISTIF
Abstract
(EN) Controllable constant power generator is based on the resistive mirror operation. The resistive mirror keeps the equality of the resistive original resistance and the resistive image resistance. The equality of these resistances is provided by maintaining the non-saturated operation of the MOSFETs (10) and (11) configuring the resistive mirror, with identical gate-to-source voltages. Adjustments of the resistive original resistance and the resistive image resistance are provided by a voltage-mode signal processing using non-inverting amplifier (1, 5), differential amplifier (2, 6), resistive voltage divider (3), and voltage transfer circuit (4, 7). The resistive mirror operation results in a constant power generation proportional to the product of the voltage of the reference voltage source (8), and the current of the reference current source (9). Generated constant power is independent of both the resistance variations of the resistive load (21) and the temperature variations. The controllability of the generated constant power can be performed by varying the voltage of the reference voltage source (8), by varying the current of the reference current source (9), and/or by varying the magnitude of the attenuation of the resistive voltage divider (3).
(FR) La présente invention concerne un générateur de puissance constante réglable qui est basé sur le fonctionnement d'un miroir résistif. Le miroir résistif maintient l'égalité de la résistance d'origine résistive et de la résistance d'image résistive. L'égalité de ces résistances est assurée par le maintien du fonctionnement non saturé des MOSFET (10) et (11) constituant le miroir résistif, avec des tensions de grille-source identiques. Des ajustements de la résistance d'origine résistive et de la résistance d'image résistive sont assurés par un traitement de signal en mode tension à l'aide d'un amplificateur non inverseur (1, 5), d'un amplificateur différentiel (2, 6), d'un diviseur de tension résistif (3) et d'un circuit de transfert de tension (4, 7). Le fonctionnement de miroir résistif résulte en une génération de puissance constante proportionnelle au produit de la tension de la source de tension de référence (8), et du courant de la source de courant de référence (9). La puissance constante générée est indépendante aussi bien des variations de résistance de la charge résistive (21) que des variations de température. L'aptitude à la régulation de la puissance constante générée peut être obtenue en faisant varier la tension de la source de tension de référence (8), en faisant varier le courant de la source de courant de référence (9), et/ou en faisant varier l'amplitude de l'atténuation du diviseur de tension résistif (3).
