In industrial combustion, commercial heating, and vehicle heating systems, the High Voltage Ignition Transformer plays the critical role of "lighting the first flame." Its performance directly determines whether combustion equipment can start reliably and operate stably. A single ignition failure can, at best, cause equipment downtime, and at worst, lead to safety incidents due to fuel accumulation. The following analysis examines its engineering value from three core technical indicators.
Core Technical Indicator 1: 20kV High-Voltage Output – Ensuring Reliable Ignition
- The HTY6-122 offers a maximum output voltage of up to 20kV, determining its reliable ignition capability under demanding conditions.
- The ignition electrode gap in burners is typically 3-6mm. Breaking down this gap requires approximately 10-20kV.
- Insufficient voltage leads to inadequate spark energy, causing ignition failure or delay.
- During low-temperature start-up, electrode carbon deposits, or poor fuel atomisation, higher voltage provides stronger ignition capability and greater tolerance for variations.
- The 20kV output is suitable for a wide range of combustion scenarios, including both gas burners and oil burners.
Core Technical Indicator 2: 50W Instantaneous Power and 10W Continuous Power
- Instantaneous power 50W Max: Sufficient energy is delivered at the moment of ignition, ensuring a strong spark and rapid ignition.
- Oil burners require high energy to overcome ignition delay. Low-temperature gas burners also require sufficient ignition energy.
- Continuous power 10W: After successful ignition, the transformer can continue operating, suitable for flame monitoring or intermittent re-ignition scenarios.
- Balanced design: High instantaneous power ensures reliable ignition, while low continuous power ensures long-term stable operation.
Core Technical Indicator 3: 6:1200 Turns Ratio and Inductance Characteristics
| Parameter | Value | Description |
|---|---|---|
| Turns Ratio | Pri:Sec = 6:1200 | Core guarantee for high-voltage output |
| Primary Inductance | 49.0µH ±20% @10kHz, 0.1V | Compatible with 7-12V input |
| Secondary Inductance | 1.9H ±20% @10kHz, 0.1V | High-voltage side energy storage capability |
| Primary DCR | 13.5mΩ ±20% | Low loss, high efficiency |
| Secondary DCR | 137Ω ±20% | High-voltage winding resistance |
- A turns ratio of 6:1200 means the secondary voltage is 200 times that of the primary.
- The primary inductance of 49µH is compatible with 7-12V low-voltage input, ensuring efficient operation under vehicle battery power supply conditions.
- The secondary inductance of 1.9H ensures energy storage on the high-voltage side, releasing sufficient energy at the moment of ignition.
- Low DCR (primary 13.5mΩ ) reduces copper loss, improves energy transfer efficiency, reduces heat generation, and improves reliability.
Engineering Reliability: Wide Temperature Operation and Compact Packaging
- Wide operating temperature range: -25°C to +105°C, covering both vehicle low-temperature start-up and industrial high-temperature operation requirements
- Compact package: 25.5×28.0×21.5mm, suitable for space-constrained PCB layouts, easy to integrate into combustion controllers, ignition modules, and similar equipment
- RoHS compliant: Meets environmental requirements, suitable for global markets
- Pin design: Standard pin spacing (16.2±0.5mm), facilitating installation and soldering
