- Step-Down Transformer:
- Primary Voltage: 240V AC
- Secondary Voltage: Given that you want to achieve 112V DC, the RMS secondary AC voltage should be around 79V AC ($112V / \sqrt{2}$).
- Rectifier Diodes (4 units for a full-wave bridge rectifier):
- Type: 1N5408 or similar high-voltage, high-current diode
- Reverse Voltage: 800V
- Forward Current: 3A
- Filter Capacitor:
- Capacitance: Start with a value like 470μF or 1000μF.
- Voltage Rating: At least 200V to handle the ripple voltage.
- Load Resistor (for simulation purposes):
- Value: Determine based on load requirements, could be something like 1kΩ to ensure nominal current draw.
Circuit Design:- Step-Down Transformer:
- Connect the primary winding to 240V AC.
- Connect the secondary winding to the bridge rectifier input.
- Bridge Rectifier:
- Connect 4 diodes in a bridge configuration.
- Anode of D1 to secondary transformer tap.
- Cathode of D1 to output (+).
- Anode of D2 to input neutral tap.
- Cathode of D2 to output (+).
- Anode of D3 to input neutral tap.
- Cathode of D3 to output (-).
- Anode of D4 to secondary transformer tap.
- Cathode of D4 to output (-).
- Filter Capacitor:
- Connect the capacitor across the rectifier output, ensuring correct polarity.
- Positive of Capacitor to output (+).
- Negative of Capacitor to output (-).
- Load Resistor:
- One end to output (+).
- Other end to output (-).
Additional Notes:- Ensure the transformer you select is rated for the required power and safety margins.
- Use protective components like fuses and varistors to safeguard against overcurrent and voltage spikes.
