Mini ZVS Induction Heating Board, Flyback Driver Heater DIY Cooker+ Ignition Coil

Product Description The Mini ZVS Induction Heating Board is a compact yet powerful high-frequency power supply module designed for DIY induction heating and flyback driving. Operating on a 5V to 12V input, this Zero Voltage Switching (ZVS) circuit minimizes switching losses and heat generation in the MOSFETs. It is ideal for heating small metal objects, creating high-voltage arcs with ignition coils, or driving flyback transformers for Jacob's ladders. The kit comes with a detachable copper heating coil, making it a "plug and play" solution for makers and hobbyists.

Key Features

• Efficient ZVS Topology: Reduces electromagnetic interference and thermal stress on electronic components.

• High Power Output: Capable of reaching up to 120W when powered by a 12V supply for rapid induction heating.

• Flyback Driver Capability: Can be used to drive ignition coils (5+5 turns primary) for high-voltage spark generation.

• Compact Footprint: Fits easily into small DIY enclosures or portable science project kits.

• Detachable Coil: Allows for easy replacement or customization of the heating element for different project requirements.

Technical Details

• Operating Frequency: Typically operates in the tens of kilohertz range depending on the LC tank circuit.

• Power Supply Requirement: Requires a high-current DC source (at least 10A at 12V) to reach maximum efficiency.

• MOSFET Cooling: Features dual on-board heat sinks to manage heat during continuous heating cycles.

• Induction Capability: Best suited for heating ferromagnetic metals (iron, steel) placed within the magnetic field of the coil.

• Push-Pull Configuration: Uses a center-tapped transformer or coil configuration for balanced power delivery.

• Capacitor Bank: Includes high-quality resonant capacitors to form the LC tank circuit essential for ZVS.

• Ignition Coil Support: When driving an ignition coil at 12V with 5+5 primary turns, it consumes approximately 30W.

• Soldering Quality: Built with thick PCB traces to handle high-current flow without excessive trace heating.

• Polarity Protection: Users must ensure correct VCC/GND orientation as the module lacks reverse polarity protection.

• Metal Melting: While capable of heating iron red-hot, it is not recommended for melting large volumes due to the 120W limit.

• Resonant Circuitry: Automatically adjusts switching frequency to match the resonant frequency of the connected load.

• Safety Feature: The ZVS design ensures that MOSFETs switch at zero voltage, significantly reducing the risk of thermal runaway.

• Module Weight: Lightweight at approximately 120g, including the coil and heatsinks.

• Dielectric Strength: The board is designed for low-voltage DC input but generates high AC currents in the output coil.

• Maintenance: Ensure the heating coil does not touch the object being heated to avoid short-circuiting the LC tank.
