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. SpletOutput ripple is a residual ac output voltage that is coherently related to the switching operation of the regulator. Its fundamental frequency is the same as the regulator’s …

Splet16. maj 2024 · In steady-state operation, we can determine the ripple current in the inductor by: Δ i L ≈ 1 22 u ⋅ 5 u = 227 m A. I used the approximate symbol because I neglect the … Splet24. jul. 2024 · The ripple voltage (across a broad range of loads from very light to quite heavy) is largely determined by the cut-off frequency and the 40 dB/decade roll-off of the second order filter. Adding more load reduces the Q of the filter and this can alter the waveform shape of the ripple but not markedly so.

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.
