This question has been boggling my mind. The capacitor input(C2) filter in this schematic helps me filter the output from the rectifier. With combination of Rchoke (is just a resistor and not an inductor) of 2.4ohm, it limits my peak current and filters the output voltage from the rectifier.
The question is why the 120 Hz output from the full wave rectifier can pass through since it is actually an RC filter. 1/2*pi*2.4*1000u = 66Hz (cut-off frequency) ?
Any help is GREATLY appreaciated.
P.S I have tried using a pi-filter which can give me higher output voltage filtering, but absorbs more current.
