## anonymous 4 years ago how can we calculate the ripple factor for the capacitive filter and pi-filter in case of full-wave by using vp-p and input voltages.which one is more effective filter?

For Capacitor Filter in case of full wave rectifier, $r=V _{r(pp)}/V _{DC}$$V _{r(pp)}\approx(1/fR _{L} C)(V _{p(rect)})$$V _{DC}\approx(1 - 1/2fR _{L} C)(V _{p(rect)})$ For π-Filter in case of full wave rectifier, $r=(\sqrt{2})/(8\omega ^{3}LC _{1}C _{2}R _{L})$ Regards, Student of EE, Read my Profile. :D
