Abstract:
1. A power circuit comprising: a switching mode power supply having a primary side and a secondary side, the secondary side electrically isolated from the primary side, the primary side connected to receive electrical power from a power input; a primary side control connected to control operation of the primary side of the switching mode power supply; a load comprising a solid-state light emitter configured to receive electrical power from the secondary side of the switching mode power supply; a controller configured to control a current being drawn by the load and to generate a primary side control signal for the primary side control; a first galvanic isolator configured to carry the primary side control signal from the controller to the primary side control; wherein all of the secondary side of the switching mode power supply, the controller and the load are galvanically isolated from the primary side of the switching mode power supply and the primary side control.
