PFC circuit
In
during full load operation at nominal 230 V
envelope of the CS pin (#4) waveforms of the L6562AT is in phase with the MULT pin (3#)
and has same sinusoidal shape, demonstrating the proper functionality of the PFC stage. It
is also possible to measure the peak-to-peak value of the voltage ripple superimposed on
the PFC output voltage due to the low value of the PFC output capacitors. In
