1000W ZVS Low Voltage Induction Heating Board Module – Flyback Driver for DIY Projects

Take your DIY metalworking and electronics projects to the next level with this powerful 1000W ZVS Low Voltage Induction Heating Board Module. Engineered for hobbyists, makers, and electronics enthusiasts, this CE-certified driver board harnesses zero-voltage switching (ZVS) technology to deliver fast, efficient, and uniform induction heating — perfect for heat treating small metal parts, melting metals with a graphite crucible, and high-frequency transformer experiments.

Key Features

• Wide Voltage Range: Operates on 12–48V DC input (power supply not included); tested successfully up to 53V
• High Power Output: Up to 1000W with a maximum input current of 20A (safe working current: ≤15A)
• Uniform & Fast Heating: Rapidly and evenly heats metals such as gold, silver, copper, and aluminum using a graphite crucible
• Heat Treatment Ready: Suitable for hardening, annealing, and other thermal processing of small metal parts
• Double-Sided Fiberglass PCB: Widened copper traces on the entire back surface for improved current handling and durability
• Enhanced Heat Dissipation: Custom 8.5mm thick substrate heat sink and M4 pillars for superior thermal management
• Versatile Application: Also functions as a powerful high-frequency inverter when a copper tube is used as a transformer
• CE Certified

Technical Specifications

Important Usage Notes

1. Kit includes the complete driver circuit board and brass piece. Power supply and cooling unit must be provided separately.
2. For continuous operation, use a fan blowing down from above to cool the resonance capacitors and other components.
3. If using a switching power supply: allow the output voltage to reach at least 12V before connecting the induction heating circuit, to prevent simultaneous MOSFET conduction and component damage during slow-start.
4. The object being heated inside the coil should not exceed 1/5 of the coil's volume (heating cylinder diameter should be less than 1/3 of the coil's inner diameter) to avoid overload.
5. Although the circuit can tolerate 20–30A momentarily, keep the working current at or below 15A for safe, reliable operation. An inline ammeter is highly recommended.
6. Recommended input voltages for general use: 24V or 36V. Higher voltage increases heating speed but also generates more heat.
7. Note: New and old board versions may be shipped randomly.

Frequently Asked Questions

Q: What power supply do I need for the 1000W ZVS induction heating board?

A: This ZVS induction heating board requires an external DC power supply in the range of 12–48V. For most general DIY heating tasks, a 24V or 36V power supply is recommended. The supply must be capable of delivering sufficient current — up to 15A for safe operation (20A maximum). The power supply is not included and must be purchased separately.

Q: Can this ZVS heating module melt metals like gold, silver, or copper?

A: Yes. When paired with a compatible graphite crucible (40mm diameter), this 1000W ZVS heating module can efficiently melt non-ferrous metals including gold, silver, copper, and aluminum. The induction heating method provides fast and uniform heat distribution, making it well-suited for small-scale metal melting and casting projects.

Q: Does the ZVS induction heating board require active cooling?

A: Yes, active cooling is required for continuous operation. It is strongly recommended to use a fan blowing downward onto the board to keep the resonance capacitors, MOSFETs, and other components within safe operating temperatures. The board features an 8.5mm thick custom substrate heat sink to assist with thermal management, but forced airflow is still necessary during extended use.

Q: What is ZVS (Zero Voltage Switching) and why does it matter for induction heating?

A: ZVS stands for Zero Voltage Switching, a technique where the power transistors (MOSFETs) switch on and off at or near zero voltage. This dramatically reduces switching losses, minimizes heat generation in the circuit, and improves overall efficiency — allowing this board to deliver up to 1000W of induction heating power while maintaining better reliability and longevity compared to conventional switching designs.
