High Frequency Transformer EL19 0.9mH/1.25mH Inductance Can Be Customized For High-frequency Circuits/switching Power Supplies/inverters
1.Product Description
This EL19 series high-frequency transformer has two standard inductance values of 0.9mH and 1.25mH, and can be fully customized according to your design requirements. It adopts high-quality ferrite core, optimized for high-frequency working environment, with high efficiency, low loss and excellent thermal stability. This transformer is an ideal core component for high-frequency, high-power density power conversion circuits such as switch mode power supplies (SMPS), photovoltaic inverters, and electric vehicle charging stations, which can effectively improve the overall performance and reliability of the system.
Detailed explanation of the core functions of EL19 series high-frequency transformers
1. Core electrical energy conversion and regulation functions
Voltage/current conversion: As a basic function of transformers, it efficiently converts input voltage and current into the required output voltage and current based on the turns ratio of primary and secondary coils, achieving energy transfer and isolation between circuits.
Impedance matching: By designing specific turns ratios, the impedance between the front and rear circuits is optimized to ensure efficient power transmission, reduce signal reflection, and improve overall system efficiency.
Electrical isolation: Establishing a reliable high insulation barrier between primary and secondary circuits, effectively blocking DC components and common mode interference, ensuring system safety and stability, is the core requirement for safe design of switching power supplies.
2. Optimization performance for high-frequency applications
High frequency and low loss operation: using low loss and high permeability ferrite cores, specially designed for high-frequency switch circuits from kHz to several hundred kHz, can significantly reduce core loss (iron loss) and coil copper loss, and improve energy efficiency.
Suppressing high-frequency noise and spikes: Excellent design and craftsmanship can effectively suppress electromagnetic interference (EMI) and voltage spikes caused by high-frequency switches, making the output purer and beneficial for electromagnetic compatibility certification.
Fast dynamic response: Thanks to high-frequency characteristics and optimized magnetic circuit design, it can quickly respond to load changes, provide stable energy supply for switching power supplies, and ensure stable output voltage.
3. Physical and reliability assurance functions
Compact power package: The EL19 magnetic core size (with an outer diameter of approximately 19mm) achieves excellent power processing capabilities within a limited volume, contributing to device miniaturization and lightweighting.
Excellent thermal stability: The magnetic core and coil materials can maintain stable performance over a wide temperature range, with good heat dissipation performance, ensuring controllable temperature rise and long-lasting service life of the transformer during continuous operation.
High structural strength and consistency: Adopting vacuum impregnation and other processes to ensure a strong bond between the coil and the magnetic core, moisture-proof and shockproof, high mechanical strength, and consistent and reliable performance of bulk products.
4. Customization and adaptation functions
The inductance value can be customized: in addition to the standard 0.9mH and 1.25mH, the required inductance can be precisely designed and customized according to the customer's specific circuit topology (such as flyback, forward, LLC) and operating frequency to optimize system performance.
Multi pin and tap configuration: Multiple sets of secondary outputs, center taps, and other coil structures can be provided to meet the needs of multiple outputs or specific circuits (such as push-pull and full bridge).
Wide range application adaptation: Its functional design enables it to perfectly adapt to various high-performance and high reliability scenarios such as switching power supplies (AC-DC, DC-DC), photovoltaic/energy storage inverters, electric vehicle charging modules, industrial control power supplies, communication equipment power supplies, etc.
