Web14 Apr 2015 · An effective implementation of a 2nd stage LC filter does require additional analysis and adjustments to make the power supply stable. Flyback converter designs that implement a 2nd stage LC filter can use less filtering capacitance and get less voltage ripple on the output load. WebFirst order filters use a single common mode choke and are the least expensive to design vs. higher-order filters. The required inductance value is just the load (in Ohms) divided by the radian frequency (2pi*f) at and above which the signal is to be attenuated, e.g. L=1.99 mH for 4 kHz cut-off into a 50 Ohm load. For a first-order filter ...
