Solar / Wind Transformer

04-15 2025 | By:

‌Solar wind power transformers‌ are transformers specially designed for use in the field of new energy, mainly used for functions such as voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. They are often used in renewable energy fields such as solar power generation and wind power generation, because these fields usually use low voltage power supply and require strong anti-interference capabilities‌

Working principle
Solar wind power transformers work based on the principle of electromagnetic induction. Taking 800V to 400V as an example, when the 800V AC voltage is input to the primary winding of the transformer, the current flows in the winding to generate an alternating magnetic field, which interacts with the secondary winding. By accurately designing the turns ratio of the primary winding to the secondary winding, the input voltage can be converted to the required output voltage. For transformers that convert 800V to 380V, the turns ratio is adjusted accordingly according to the specific voltage conversion requirements‌

Construction and materials
In terms of construction, transformers usually use silicon steel sheets with high magnetic permeability and low hysteresis loss as core materials. High magnetic permeability helps the magnetic field to be efficiently conducted in the core, reducing energy loss and improving conversion efficiency. Low hysteresis loss can ensure that the core heats up less under the repeated action of the alternating magnetic field, ensuring the stable operation of the transformer. For windings, high-quality insulated wires are used, and the number of turns, winding process and insulation treatment of the windings are strictly controlled to ensure good electrical insulation performance and prevent leakage, short circuit and other faults.

Application Fields
Solar and wind power transformers are widely used in new energy fields such as solar power stations and wind farms. They can convert low-voltage electricity generated by solar and wind energy into high-voltage electricity suitable for grid access, ensuring the stable operation of the power system.
