✅ Pure AC to DC Full Bridge Rectifier!
Let’s explore six setups (A to F) of a circuit converting AC to DC with a bridge rectifier (P1). Each setup adds filtering components to smooth the DC output, improving the waveform step by step.
A: No Filter
Setup: Bridge rectifier (P1) and resistor (R) as load.
Waveform: Very rough, sharp peaks reaching 16V and dropping to 0V.
B: Adding Inductor
Adds inductor (Z) in series with R.
Waveform: Smoother, reducing peaks and dips but still fluctuates between 8V and 16V.
C: Using Capacitor
Replaces inductor with capacitor (C1) in parallel with R.
Waveform: Much smoother. Capacitor stores and releases energy, reducing ripples to around 8V.
D: Inductor + Capacitor
Combines inductor (Z) in series and capacitor (C1) in parallel with R.
Waveform: Smoother than C, less fluctuation, voltage more stable.
E: Pi-Filter
Adds second capacitor (R1) after inductor, forming “pi” with C1, Z, and R1.
Waveform: Almost flat, around 12V with minimal variation.
F: Double Pi-Filter
Adds third capacitor (C2) after pi-filter.
Waveform: Smoothest, nearly perfect line at 12V with almost no ripples.
Key Comparison
A: Very rough output.
B: Smoother but still fluctuating.
C: Significant improvement.
D: Combines filter elements for better smoothing.
E: Almost flat with pi-filter.
F: Nearly perfect DC output.
