The reason is that the reverse EMF produced by inductive loads produces an out-of-phase wave back to the triac so that the triac never sees zero volts. Thus the triac never ceases conducting, resulting in total loss of control. There are snubbe ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
