Note 1: This value of R
ensures that the line current will be zero around
the zero-crossing of the line voltage, which is the required condition for
low-distortion line current.
Note 2:
This value of R
ensures that the sum of the voltage drop across
R
(caused by the peak inductor current) and the voltage drop across R
(caused by the instantaneous value of the stabilizing current) is equal to
the threshold voltage of the current-control detector at the peak of the
line voltage.
