This makes the true sense current 2.5V/12K = 208 mA. The upper resistor is
Make this resistor a 1Mohm and a 910K ohm resistor in series, each with a
1/2W rating.
The compensation of the voltage error amplifier should be a single-pole
rolloff with a unity gain frequency of 38Hz. This is required to reject the fun-
damental line frequencies of 50 and 60Hz. The feedback capacitor around the
voltage error amplifier becomes
Designing the input EMI filter section
I will be using a second order, common-mode filter. The difficulty in consider-
ing an input conducted EMI for this power factor correction circuit is its vari-
able frequency of operation. The lowest ...
