... As mentioned before, the sensorless commutation requires a minimum amount of speed to work. This is because the amplitude of the BEMF is proportional to the angular velocity of the rotor. Below the speed limit, the signal noise ratio of the BEMF signal that is superposed by the PWM signal is too low ...

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.
