High efficiency: high operating efficiency, low heat loss, can effectively save energy, and minimize energy loss during transmission.
Safety: using new materials and processes, with high shock resistance and heat resistance, can effectively avoid the occurrence of safety accidents.
Reliability: simple structure, easy maintenance, low maintenance cost, higher reliability and stronger economy than traditional transformers.
Space saving: small size and volume, small footprint, can be widely used in buildings, rail transit, automobiles and communications and other fields with high space requirements.
High power density: due to its small component size and excellent temperature dissipation characteristics, it can be tightly packaged with related semiconductor devices and inductors Together, high power density is achieved, and the current density can reach 30A/module;
Low cost: It is composed of a small number of related cheap components, easy to assemble, and low cost.
Improve the cost of connecting components: small leakage inductance, low switching loss, and reduced stress on the connected components, so the components connected to it can use low-cost low-power rated components.
Good heat dissipation characteristics: It has a high surface area to volume ratio and a very short thermal channel, which is conducive to heat dissipation. The turn-to-turn loss between the primary and secondary windings is very small, and the unique geometric shape of the magnetic core can also effectively reduce the core loss. It can work between -40℃ and 130℃ and can achieve high magnetic flux density;
Low leakage inductance: winding The coupling between the windings is good, which can keep the leakage inductance between the winding turns at a minimum. The connection from the output end to the auxiliary components is short and tightly assembled, which makes the leakage inductance between the windings minimized.
Excellent high-frequency characteristics: It can be designed as a high-frequency transformer with a wide operating frequency range, which can provide an economical and good transformer module, solving the problem of increased switching loss and overheating when the traditional transformer operates at high frequency, and can work between 100kHz and 500kHz.
Even current distribution: The secondary winding of a typical high-frequency transformer has several coils in parallel, and each secondary winding is coupled to the same primary winding, so the ampere-turns generated by the secondary winding current The ampere-turns generated by the primary winding are equal (ignoring the excitation current). This feature is particularly useful for parallel rectifier circuits. The winding current is evenly distributed, and no current-sharing resistors or other components are required in parallel rectifier circuits.
Simple structure: It consists of a small number of components and a minimum number of windings. This module is particularly suitable for automated assembly.
Low profile: The magnetic core used is small and can be arranged on the surface of a flat plate. The size of each magnetic core unit is usually in the range of 8mm to 25mm.
High insulation strength: It is easy to insulate according to the required number of insulation layers and thickness, and can be dielectrically insulated according to the customer's requirements for leakage distance. The withstand voltage between the primary and secondary windings is greater than 40,000V.
It can be seen that different needs require different transformers. At the same time, with the development of technology, the performance of transformers is also constantly optimized and improved.
