Controlling the pass-element power is the safest and fastest way to charge the load capacitance. Pass-element protection is maintained while boosting efficiency and reliability.

Since halogen bulbs typically are driven with 12 or 24 V due to their excellent efficacy at those voltages, buildings have been wired with 12- and 24-V ac transformers for halogen lighting. Therefore, replacing existing halogen lighting with LEDs requires only an LED driver to convert the 12- or 24-V ac to an appropriate dc voltage. A suitable circuit is a switch-mode regulator LED driver designed for ac lighting that requires a high power factor (PF).
