Abstract

An electronic lighting system with a driver includes transformers that are dedicated to particular lamp receptacles that include interloper diode and resistor sets that fine tune the functioning of the driver. A buck converter and power factor correction, and a zeta scan are included. A comparator circuitry receives an external control signal and compares it to feedback from the output side of the circuitry, and thereby controls a Pulse Width Modulation (PWM) circuitry, which cooperates with feedback-based MOSFETs and a MOSFET gate driver circuit. This aids in dimming capabilities, recognizes and corrects for outages and recognizes and corrects for changes in the different size lamps that a user may install.
