🎬 ZVS Driver Circuit Using IRFZ44N | Wireless Power & Flyback Transformer Driver | DIY High VoltageIn this video, I’m building a Zero Voltage Switching (ZVS) driver circuit using IRFZ44N MOSFETs, a 1µF 400V capacitor, and a 30-0-30 transformer for efficient high-frequency switching. This powerful circuit is ideal for driving flyback transformers, creating wireless energy transfer, or experimenting with high voltage effects.
⚡ Why ZVS?
ZVS (Zero Voltage Switching) ensures that the MOSFETs switch on only when the voltage across them is near zero — this reduces heat, increases efficiency, and protects the components during high-speed operation.
🔧 Updated Project Features:
🔋 Power Supply: 12V to 24V DC (IRFZ44N safe up to 55V)
🔁 Oscillates automatically with self-resonant LC circuit
🔧 Uses 100Ω, 1W resistors instead of 470Ω for faster gate charging
🔄 Includes 1µF, 400V capacitor for strong LC resonance
🔌 30-0-30 Transformer used for center-tapped primary
⚡ FR107 fast recovery diodes (1A, 700ns) for gate protection
🔒 12V Zener diodes for MOSFET gate clamping
💨 10kΩ resistors to discharge gates and prevent false triggering
📦 Main Components:
2x IRFZ44N N-Channel MOSFETs
