In this video, we'll see how to calculate the smoothing capacitance after rectification for a given ripple using a widely used empirical formula that provides the capacitance value based on the output current, frequency, and allowable ripple voltage. I want to reduce the ripple of the NuovaElettronica LX558 power supply (video 827: • 0827: Riparo e modifico l' alimentatore Nu... ), so I'm installing a Capacitor Bank in parallel to increase the capacitance to over 10,000 uF. However, other components also need to be adjusted... otherwise, they'll blow up... we'll see how in the video.
