Patent abstract
A driver circuit provides power from a power source to a load. The driver circuit includes a surge protector, an input stage (e.g., full wave rectifier), a controller, an overvoltage protection circuit, and an output stage (e.g., a half bridge inverter). The input stage receives power from the power source and provides a direct current (DC) power rail. The controller operates the output stage to provide power from the DC power rail to the load. The overvoltage protection circuit shuts down the controller when the DC power rail exceeds a predetermined voltage. This ceases operation of the output stage, protecting the output stage from damage while the DC power rail is above the predetermined voltage.
