There is a comprehensive range of microelectronics performing different functions. Trigger transformer is one of the most underrated microelectronics. However, they are crucial in the world today. For gas-filled cold cathode devices, a trigger transformer is a low-duty firing transformer that starts the pilot currents that generate the main start-up currents.
Although it is also feasible that the primary winding is a part of the much larger secondary winding, it is typically made so that the secondary winding has a turn count several times higher than the primary winding. As a result, the trigger transformer can deliver trigger voltages that would not otherwise be possible from the main supply because of the enormous turn ratio of its windings.
Since 1956, Excelitas has been producing high-voltage trigger transformers. Various input and output voltages are provided for their standard legacy designs. Modern manufacturing processes offer high performance, including vacuum impregnation, vacuum encapsulations, and meter-mix dispensing systems.
Applications of Trigger Transformers
The following are some of the most popular application devices that you can use the trigger transformer can with:
- Arc lights
- flashing lights
- Bright lights
- Bright Tubes
- Thermo-gas lasers
- Fluorescent lighting
Cons of Trigger Transformers
The flexibility of connections: Flash bulbs are one of the most popular uses for trigger transformers. You can utilize multiple flash bulbs to produce vibrant displays in various applications. As several transformers can be arranged together to provide this display, trigger transformers are helpful in such situations.
High-Frequency Designs: Ferrite cores operate at high frequencies and are used in many trigger transformer designs. These enable minimal power losses, extending the transformers’ useful lives. These were created specifically for use with portable circuits.
Application Device Protection: Because high voltage is used, there is always a chance that application device components could be harmed. Device safety can be guaranteed by the design of trigger transformers. The device can build current limitations into the design of the transformer to prevent the transformer tube from drawing excess current.
Benefits of Size: Trigger transformers can be developed and produced in various sizes depending on the application requirements. Transformers of smaller sizes are more economical than those of larger sizes. In cases where a series trigger transformer is used, larger-sized transformers can deliver a higher current.
Types of Pulses in Trigger Transformers
Series Triggering
The discharge current from the energy storage capacitor goes via the secondary winding of the trigger transformer in series injection triggering instead of external triggering. Therefore, the transformer’s secondary winding must be built to handle the entire discharge current. Thus, compared to an external trigger transformer, this type of trigger transformer is more significant, heavier, and more expensive.
The trigger transformer’s inductance, a component of the discharge circuit, can be used to modify the current pulse wave shape of the energy storage capacitor.
External Triggering
In external triggering, a thin ionized streamer is produced between the lamp’s anode and cathode, employing a high voltage trigger pulse. A tiny nickel wire wrapped around the surface of the lamp envelope can be used to couple this voltage to the lamp.
Types of Trigger Transformers
Pulse Trigger Transformers
For their load circuits, industries like power distribution, digital, and telecommunications need quick and robust electrical pulses. Step up or step down transformers cannot meet this type of need. A specialized transformer is required to supply the necessary power. Custom Coils offers a unique pulse transformer circuit for these applications. Equipment for transmitting signals, switching mode power supply with low and high energies, and many other things require pulse transformers. We offer specially designed pulse transformers that reduce voltage drop and pulse distortion. They can be run at high frequencies and convert adequate power for applications with heavy loads.
The team of professionals at Excelitas works directly with customers from various sectors as a leading bespoke pulse transformer manufacturer to comprehend their mechanical and electrical needs. The design and manufacture of a custom transformer start with a thorough examination of the client’s requirements and concludes with the optimum choice of materials, conductors, and other components.
Low Profile Trigger Transformers
The design of the trigger transformer has several advantages for industrial applications. UI laminated cores are used in the construction of low-profile power transformers. The external electromagnetic emissions can be decreased thanks to these cores. Opposing fields in the legs of the core can be canceled thanks to the semi-toroidal structure. LPC transformers are constructed using EI laminations. This sort of lamination is renowned for being reasonably priced and easily accessible.
These goods have non-concentric windings because they are semi-toroidal in shape. This lessens the capacitance between the windings. Additionally, it does away with the necessity for an electrostatic shield. As a result, Excelitas can create low-profile power transformers in various input and output voltage options.
Ferrite Transformers
In essence, ferrites are non-conducting compounds with ceramic-like qualities that contain ferromagnetic and permeability characteristics. Iron oxides, manganese, zinc, and nickel are all found in combination in the cores of ferrite transformers. Their high resistivity virtually eliminates eddy currents. Ferrite core transformers are one of the Excelitas specialties. The professionals at this company have practical experience designing and making ferrite core transformers. They provide high-frequency ferrite core transformers and standard and custom ferrite transformer designs. In transformer applications where the supplied voltage has a high frequency, ferrite cores are beneficial. Excelitas technicians will be pleased to work with you to satisfy your specific needs and provide you with an estimate for your next task if you require more extraordinary frequency designs.
DC Igniter
In heated pressure washers and heating systems, sparks are produced by DC igniters. This electrical igniter creates an electric spark in the heating chamber that heats the fuel just enough to begin burning. These DC igniters frequently use direct current to operate, hence the name. Getting these electrical igniters from a reputable DC igniter manufacturer is crucial if you want excellent efficiency, which entails minimal power consumption and optimal electrical spark generation.
In conclusion, Excelitas is a market leader in the design, testing, and production of energetic products for electrical safety, commencement, activation, and explosion applications. With more than three decades of combined experience, our team of scientists, engineers, and manufacturers has gained a solid understanding of every facet of energy system efficiency and validation.
