2. Setup Instructions
Careful setup is crucial for safe and effective operation. Ensure all connections are secure before applying power.
2.1 Power Supply Connection
Connect a DC power supply within the 12V to 30V range to the input terminals labeled 'DC12-30V Input Voltage' and 'GND'. The module requires a stable power source capable of supplying sufficient current (e.g., 10A for optimal performance).

2.2 Output Load Connection
Connect your desired load (e.g., flyback transformer, induction heating coil) to the output terminals. For flyback transformers, ensure the primary coil is correctly wound and connected. Refer to the circuit diagram for proper wiring.

Ensure adequate airflow around the module during operation, especially during high-power applications, to support its internal cooling mechanisms.
5. Troubleshooting
If you encounter issues with your ZVS Driver Module, refer to the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output/No oscillation | Incorrect power supply voltage or current; Loose connections; Incorrect load wiring; Faulty component. | Verify input voltage is between 12V-30V DC and power supply can deliver sufficient current (e.g., 10A). Check all wiring for secure connections. Ensure the load (e.g., flyback primary coil) is correctly wound and connected as per diagrams. |
| Module overheats quickly | Excessive load; Insufficient cooling; Short circuit in load. | Reduce the load or operating time. Ensure adequate ventilation around the module. Check the load for any short circuits. |
| Unstable oscillation | Improperly tuned load; Power supply fluctuations. | Some loads, especially induction coils, may require minor adjustments (e.g., number of turns, wire gauge) to achieve stable resonance. Ensure your power supply is stable and provides clean DC power. |
| Arcing at connections | Loose connections; High voltage spikes. | Tighten all connections. The module includes snubber networks to mitigate spikes, but ensure your setup is robust. |
