SMPS circuits offer an efficient way to reduce AC from a mains source to any desired level for powering low-voltage circuits, though this comes at the cost of components such as control ICs, switching ...

Though a constant current source is used here for power control, it can be replaced by any other control sources. The optical isolation will keep the control sources safe from the AC. Though this ...
