A hybrid power control system using dynamic power regulation to increase the dimming dynamic range and power control of solid-state illumination systems

摘要

A hybrid power control system provides dynamic power control to electroluminescent illumination systems in which a power source can supply any one of a range of AC or DC voltages. One or more switch mode power supplies incorporate one or more linear and switch mode regulator circuits combined to dynamically control current, voltage and power to the illumination system.  A microprocessor or other integrated circuit device receive and send control information in order to regulate the power to a light emitting device One or more output drive stage(s) capable of delivering a wide dynamic current range, channel bonding and protection circuitry compatible with standard or common anode illumination systems.
