A dimming power supply includes a power source, a full bridge rectifier with four nodes, a control switch and a controller. The first node is connected to the power source, the second is connected to a load output, and the third is connected to a reference voltage node. The control switch is connected between the fourth node and the reference voltage node. The controller is connected to a control input of the control switch. The controller is adapted to adjust a voltage or current through the load output. |
