Switching ripple
SpletThe switching circuit typically operates from 25kHz up to 500kHz and is a source of EMI. Noise entering from the mains has two components: common mode and differential mode. Common mode relates to noise measured between either live or neutral and earth. Differential noise is between live and neutral. SpletThe switching ripple (at the switching frequency) caused by the change in charge of the capacitor is very small compared to the undampened ringing of the output switch, which we will refer to as output noise. Generally, this output noise is in the 10 MHz to 100+ MHz range, well beyond the self-resonant frequency of most ceramic output capacitors.

SpletLecture 5 contains the material on DC-DC converters. It first derives the basic DC analysis, then proceeds to derive voltage and current ripple. In general, the ripple current / voltage will decrease as switching frequency goes up as their is less time for the inductor/capacitor to charge/discharge between cycles, creating ripple.

SpletThe amount by which the current changes during a switching cycle is known as the ripple current and is calculated by the formula; V1 = L x di/dt V1 is the voltage across the inductor, di is the ripple current, and dt is the duration that the voltage is applied. This shows that the value of ripple current is dependent upon the value of inductance.
