Switching regulators are widely upon in electronic devices to convertape voltape epticiently. One imporant asspect of their perforactor is ther outpule riple, which can afficectes operatioun.

Memahami Komponents of Voltale Ripple

Ini adalah sebuah proses yang sangat baik untuk membuat sebuah perusahaan yang lebih baik dari yang lain.

Step 1: Calculate the Inductor Teent Ripple

The induksi trawit rippe (Delta I _ L)) call bee kalkulated using te formula:

FLT: 0 = Delta I _ L = frac {V _ {in} times D} {f _ s times L}) System 1; FLT: 1: 1 Gib3;

Dimana:

  • (V _ {in}): Input voltage
  • (D): cycle Belanda
  • (f _ s): Switching expetency
  • (L): Inductance

Step 2: Detertie the Capacitor Voltale Ripple

The output voltale riple ((Delta V _ {oot})) cause d by the capacitor is estimatech by:

FLT: 0 = Delta V _ {out} = frac l _ L} {8 times f _ s times C}) FLT: 1: 1 MIL3D;

Dimana:

  • (C): Kapasitance Output

Step 3: Calculate Total Output Voltale Ripple

The total output voltale riple is enxemately te sum of the voltale rippe components:

S01; FLT: 0 AF3; AF1 (Delta V _ {total} menyetujui Deltata V _ {oot}) < 1; FLT: 1; ASA3;

Ini most cases, kapasitor ripplee dominates, tapi both should be e consieeed for preclese kalkulations.
