Toroidal Transformer For Audio Amplifiers 50/60hz 220v 240v 12v 24v
5a 120w
Product performance:
The iron core of the toroidal transformer is made of continuous continuous oriented silicon steel strips. After annealing, a highly consistent magnetic flux guidance will be formed. The pass density is higher because the toroidal transformer can achieve a high electrical efficiency of 95%.
The working principle of a toroidal transformer is essentially the same as that of a transformer.
The iron core of the toroidal transformer is made of high-quality cold-rolled silicon steel sheet (the thickness of the sheet is generally less than 0.35mm), which is rolled seamlessly, which makes the performance of the iron core better than the traditional laminated iron core.
The coil of the toroidal transformer is evenly wound on the core, and the direction of the magnetic field lines generated by the coil almost completely coincides with the magnetic circuit of the core. Compared with the laminated type, the excitation energy and core loss will be reduced by 25%.
The principle of the toroidal transformer is the same as that of the transformer, both of which are based on the basic principles of electro-magnetic and magneto-electric conversion.
Application:
Application in other fields
Toroidal transformers can also be used in power inverters of various sizes, such as solar and wind power generation systems. This high-efficiency toroidal transformer with a low-loss iron core can greatly improve the overall efficiency of the inverter power supply.
Advantages of Toroidal Transformers:
1. High electrical efficiency
The core has no air gap, the stacking coefficient can be as high as 95% or more, the magnetic permeability of the core can be 1.5~1.8T (the laminated core can only be 1.2~1.4T), the electrical efficiency is as high as 95% or more, and the no-load current is only the laminated type. 10% of;
2. Small size and light weight
The weight of the toroidal transformer can be reduced by half compared to the laminated transformer. As long as the cross-sectional area of the iron core is kept equal, the toroidal transformer can easily change the ratio of the length, width and height of the iron core, and can be designed to meet the required external dimensions;
3. Less magnetic interference
The core of the toroidal transformer has no air gap, and the windings are evenly wound on the toroidal core. This structure leads to low magnetic flux leakage and low electromagnetic radiation. It can be used in high-sensitivity electronic equipment without additional shielding, such as applications in low Level amplifiers and medical equipment;
4. Less vibration and noise
The iron core has no air gap, which can reduce the iron core.
