    Abstract: A system including a first transistor, a second transistor, and a comparator. The first transistor is configured to supply a first current to a first load connected to a first terminal of the first transistor. The second transistor is configured to supply a second current to a second load connected to a first terminal of the second transistor, wherein the first current and the second current have a predetermined ratio. The comparator is configured to compare a voltage at the first terminal of the first transistor or a voltage at the first terminal of the second transistor to a reference voltage, and to adjust, based on the comparison, biasing of the first transistor and the second transistor to maintain the predetermined ratio between the first current and the second current.

    Abstract: A triac dimming system for solid-state loads, LEDs, is based on a flyback DC/DC converter and includes a transformer. The transformer includes a first coil and a second coil. The first coil is configured to receive a first voltage based on an output of a PWM switching circuit. The second coil is configured to generate a first current based on the first voltage to power the solid-state load. The system also includes a third coil. The third coil is configured to generate a second supply voltage based on the first voltage. A bleeder module includes a PWM controlled switch and is connected to the secondary load side of the transformer.
