Current in-rush limiting circuit using switchable current limiting arrangement

An apparatus, comprising:

• first and second input terminals configured to be connected to a source of input power;
• a conversion circuit operably connected to the first and second terminals, the conversion circuit including a first inductive winding coupled between the first terminal and a switching device, a rectifier coupled between the first inductive winding and a first output, and a capacitor coupled between the first output and circuit ground;
• a second winding inductively coupled to the first inductive winding;
• a triac having a control input operably coupled to the second winding, the triac having a load path series-coupled between the second input terminal and circuit ground;
• and
• a current limiting resistive device operably coupled between the second input terminal and circuit ground.
