How to calculate Corner frequency for Series LC Filter/

Decay rate for LC filter is = -40dB per decay. Fc => Corner Frequency. Fsw => Switching frequency. Subtituting all the values as mentioned, you can find the required Fc i.e; Fc = 20kHz/ (10^ (-100/-40)) Fc = 63.24Hz. Since now we know the Corner frequency, we can find the required value for the capacitor i.e;
