Introduction to Adjustable Power Supplies
Variable power supplies find application in electronics laboratories, test equipment, and in home projects. The 0-30 V 10A power supply will enable users to safely supply different circuits with varying voltage and current. The supply achieves stability in the volume of voltages at different load conditions because it uses the linear regulators, MOSFETs, T s, and potentiometers.
>Key Formulas for Full-Wave Bridge Rectifier:
- Vdc = (2 × Vm)/π ≈ 0.637 × Vm
- Vrms = Vm/√2
- Ripple Factor = (1.21 for full-wave)
- Efficiency = 81.2%
full-wave rectifier explanation
A full-wave bridge rectifier is a circuit that changes AC (alternating current) to DC (direct current) with four diodes connected in a most important position called the bridge position. This project describes the circuit, working principle, and benefits of a full-wave rectifier as compared to a half-wave rectifier. This project is of great importance in the design of power supply, a very important concept to students as well as beginners in electronics. It indicates how the diodes conduct alternating runs of the AC and make a smoother output of DC. It consists of 4 diodes (1N4007), a center-tapped or regular transformer and a filter capacitor, and a load resistor. Formulae, working explanations, and sample values of voltages are provided in this tutorial to understand.
bridge rectifier circuit
| AC Input (Vrms) | Transformer Vm | DC Output (Vdc) | Load Current (I) |
|---|---|---|---|
| 230V | 12V | 7.64V | 150mA |
| 110V | 6V | 3.82V | 75mA |
