Formula:
To calculate the required capacitance (C) for smoothing ripple voltage in a typical full-wave rectified DC power supply, the following formula is used:
C = Iload / (2 × f × Vripple_pp)
- C = Capacitance in Farads (F)
- Iload = Load Current (Amperes, A)
- f = AC Input Frequency (Hertz, Hz - e.g., 50Hz or 60Hz)
- Vripple_pp = Desired Peak-to-Peak Ripple Voltage (Volts, V)
This formula helps determine the capacitor size to maintain a stable DC output by minimizing voltage fluctuations.
