Introduction
High brightness LEDs are becoming a prominent source of light and often have better efficiency
and reliability than conventional light sources. While LEDs can operate from an energy source
as simple as a battery and resistor, most applications require an efficient energy source not
only for the reduction of losses, but also to maintain the brightness of the LED itself. For
applications that are powered from low voltage AC sources typically used in landscape lighting
or low voltage DC sources that may
