Patent

CA 2343322

A battery polarity insensitive amplifier utilizes a power management architecture to reduce the size of the circuitry used to accomplish the polarity correction function. An efficient Class D amplifier (146) and a compact voltage multiplying driver circuit (72) reduce the size of the battery polarity insensitive amplifier circuit (70, 72, 146).

Cet amplificateur insensible à la polarité de la batterie met en oeuvre une architecture à gestion de puissance pour réduire la taille des circuits utilisés pour la fonction de correction de polarité. Un amplificateur classe D efficace (146) et un survolteur compact (72) permettent de réduire la taille de ce circuit amplificateur (70, 72, 146) insensible à la polarité de la batterie.
