How to Convert Positive Voltage to Negative Using NE555 & Charge Pump in Proteus

This video demonstrates a negative voltage converter using an NE555 timer and a charge pump circuit in Proteus Software. The circuit converts +30V to -29V using pulse generation and capacitor charging/discharging principles.

Key Features:

NE555 Monostable Mode: Generates precise timing pulses.
Charge Pump Mechanism: Inverts voltage using capacitors and diodes.
Protection Capacitors: Reduces noise and ensures stable operation.

What you’ll learn:

How to create negative voltages from positive supplies.
Role of charge pumps in voltage inversion.
Importance of timing components (R/C) in 555 circuits.
Simulating real-world circuits in Proteus.

⚠️ Safety Note: Always use isolation transformers and follow safety protocols when working with high-voltage loads.
