Ripple Factor and DC Output Voltage Calculation
The output voltage (V_dc) and ripple factor (r) can be calculated using the following formulas.
- DC Output Voltage (V_dc):
- For a full wave rectifier, the DC output voltage is approximately:
V_dc = (2 * V_peak) / π
- Here, V_peak = 40V.
- Thus, V_dc = (2 * 40) / π ≈ 25.46V
- Ripple Factor (r):
- The ripple voltage (Vr) can be estimated as:
Vr = I_load / (f * C)
- Where:
- I_load = 0.2A
- f = 100Hz (since it’s a full wave rectifier, frequency is doubled from input frequency)
- C = 49µF = 49 x 10^-6 F
- Calculating Vr:
Vr = 0.2 / (100 * 49 x 10^-6) ≈ 40.82V
- Ripple Factor (r):
- The ripple factor is defined as:
r = Vr / V_dc
- Thus, r = 40.82 / 25.46 ≈ 1.60
Design of Full Wave Rectifier with LC Filter
To design a full wave rectifier with LC filter to provide 10V DC at 100mA with a maximum ripple of 2%, follow these steps:
- Output Specifications:
- Desired V_dc = 10V
- Load Current (I_load) = 0.1A
- Maximum Ripple Voltage (Vr_max) = 2% of 10V = 0.2V
- Required Capacitance (C):
- Use the formula: C = I_load / (f * Vr_max)
- For 50Hz input, f for full wave = 100Hz
- C = 0.1 / (100 * 0.2) = 0.005F or 5000µF
- Inductance (L):
- Choose L based on the desired ripple current and capacitor value.
- Use L = (Vr_max * C) / (I_load)
- L = (0.2 * 5000 x 10^-6) / 0.1 = 0.01H or 10mH
- Transformer Specifications:
- The transformer should provide a peak voltage higher than V_dc to account for voltage drops across diodes and ripple.
This configuration will yield a stable 10V DC output with a ripple within the specified limits.
The output voltage (V_dc) and ripple factor (r) can be calculated using the following formulas.
- DC Output Voltage (V_dc):
- For a full wave rectifier, the DC output voltage is approximately:
V_dc = (2 * V_peak) / π

Vr = I_load / (f * C)
- Where:
- I_load = 0.2A
- f = 100Hz (since it’s a full wave rectifier, frequency is doubled from input frequency)
- C = 49µF = 49 x 10^-6 F
- Calculating Vr:
Vr = 0.2 / (100 * 49 x 10^-6) ≈ 40.82V
- Ripple Factor (r):
- The ripple factor is defined as:
r = Vr / V_dc
