Choosing thee correct inductor and capacitor values is essential for thee proper functiong of power converters. Accurate calculations ensure efficiency, stability, and performance. Thi article provides a step bystep guidee to perfom these calculations effectively.

Obliczanie tej wartości Inductor Value

Te induktor wartości te są pełne i są zbyt stabilne.

  • Identify the input voltage (Vin), output voltage (Vout), andchange dispeciency (f).
  • Określić, że maximum allowable current ripple (ΔI).
  • Use the formula: prevent 1; present 1; FLT: 0 presenta3; presenta3; L = (Vin - Vout) * Vout / (ΔI * f * Vout) presenta1; presentation 1; FLT: 1 presentation 3; presentation 3;.

Adjuss thee inductance value based on thee desired ripples current. A contrione is to set ΔI to 20- 40% of thee maximum load current.

Kalkulating thee Capacitor Value

Te filtry pojemności voltage ripples and stabilizates thee output. To select thee right capacitor:

  • Określić, że maximum voltage ripple (ΔV) akceptuje at te out put.
  • Identify the load current (Iload) andchanding frequency (f).
  • Thy formula: Xi1; Xi1; FLT: 0 Xi3; Xi3; C = ΔI / (8 * f * ΔV) Xi1; Xi1; FLT: 1 Xi3; Xi3;.

Choose a capacitor wigh a voltage rating higher than the maximum output voltage and consider low equivalent serie resistance (ESR) for better performance.
