5. Setup and Wiring
The LiebeWH High Voltage Flyback Transformer Module requires careful wiring to ensure correct and safe operation. The primary winding has two parts: a main winding and a feedback winding. The low voltage winding is on the outer layer, and the high voltage winding is encapsulated in the inner layer.
Figure 5.1: LiebeWH High Voltage Flyback Transformer Module. This image shows the compact design of the module with its input (red and green) and output (multiple thin copper) wires clearly visible.
5.1 Input Connections (Low Voltage)
- Identify the two thick and thin coiled copper wires. These are the positive poles for the primary winding.
- One wire corresponds to the 'main winding' and the other to the 'feedback winding' head.
- Connect these two wires to the positive terminal of your 3.7V-4.2V DC power supply.
- The remaining wire (typically green or another color, as shown in images) is the negative input. Connect this to the negative terminal of your power supply.
- Important: Do not confuse the low voltage input windings with the high voltage output windings. Incorrect connection can damage the module or your power supply.

5.2 Output Connections (High Voltage)
- The high voltage output is typically from the thicker, insulated wires that are part of the inner winding.
- Ensure these output wires are properly insulated and routed away from other components and conductive surfaces.
- Maintain a safe distance between the high voltage output terminals (0.5-1 cm for ignition distance).
6. Operating Instructions
- Verify Connections: Double-check all input and output wiring according to Section 5.
- Ensure Safety: Confirm that all safety precautions from Section 2 are in place. Wear appropriate personal protective equipment.
- Apply Power: Connect the 3.7V-4.2V DC power supply to the module.
- Observe Operation: Upon power application, the module will begin generating high voltage. While no crackling sound may be heard in the air, the high voltage output will generate significant heat and can ignite flammable materials.
- Power Off: Disconnect the power supply when operation is complete. Allow sufficient time for any residual charge to dissipate before handling.

7. Maintenance
- Keep the module clean and free from dust and debris.
- Store in a dry environment, away from moisture and extreme temperatures.
- Regularly inspect wiring for any signs of damage or wear. Replace damaged wires immediately.
- Ensure proper ventilation during operation to prevent overheating.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No high voltage output | Incorrect input voltage or current; incorrect wiring; faulty power supply. | Verify input voltage (3.7V-4.2V) and current capacity of power supply. Check all wiring connections, especially the primary and feedback windings. Test power supply independently. |
| Module overheating rapidly | Excessive input current; insufficient ventilation; short circuit in output. | Ensure input current does not exceed 2A. Provide adequate ventilation. Check for any unintended contact or short circuits at the high voltage output. |
| Weak or inconsistent spark | Low input voltage; poor contact at output terminals. | Confirm input voltage is within the specified range. Ensure clean and secure contact at the high voltage output points. |
