How to Build a 15V Dual Power Supply Using 7815 & 7915 Regulators in Proteus | Step-by-Step Tutorial

This video demonstrates a symmetrical dual-polarity power supply using 7815 (positive) and 7915 (negative) voltage regulators in Proteus Software. The circuit generates ±15.0V outputs from a single AC input, ideal for applications like op-amp circuits, analog signal processing, and audio amplifiers. Key Features: Transformer & Bridge Rectifier: Steps down 220V AC to a lower AC voltage and converts it to pulsating DC. 7815 Regulator (U1): Stabilizes the positive output to +15.0V. 7915 Regulator (U2): Stabilizes the negative output to -15.1V. Filter Capacitors (2200µF, 10nF): Reduce ripple voltage for smooth output. Output Meters: Real-time visualization of both ±15V outputs in Proteus. How It Works: AC-to-DC Conversion: The transformer (TR1) steps down 220V AC → 12V AC. The bridge rectifier (BR1) converts AC to pulsating DC. Voltage Stabilization: The 7815 regulator (U1) stabilizes its output to +15.0V. The 7915 regulator (U2) stabilizes its output to -15.1V. Ripple Filtering: Input capacitors (C1, C2: 2200µF) smooth pulsating DC. Output capacitors (C3–C8: 10nF) eliminate residual ripple. What you’ll learn: How to create symmetric ±15V outputs from a single AC source. Role of capacitors in filtering and stabilizing voltage. Importance of dual-polarity power supplies in analog circuits. Simulating real-world circuits in Proteus. ⚠️ Safety Note: Always use isolation transformers and follow safety protocols when working with high-voltage loads. 🔔 Subscribe for more tutorials, and hit the bell for updates!
