With the continuous surge in demand for photovoltaic energy storage, electric vehicle charging facilities, and industrial and commercial energy storage systems worldwide, high-frequency transformers, as the core magnetic components for electrical energy conversion, are witnessing an unprecedented technological revolution.
Traditional high-frequency transformers have long relied on ferrite cores. However, under the high-frequency, high-power, and high-temperature conditions required by new energy applications, the problems of low saturation magnetic density of ferrite and high temperature loss have become increasingly prominent. To break through this bottleneck, Guangdong Haoli Electronics Co., Ltd. has accelerated the industrialization application of amorphous and nanocrystalline magnetic cores. The latest batch of non-ferromagnetic and nanocrystalline high-frequency transformers have demonstrated significant advantages in actual tests: within the typical switching frequency range of 20kHz to 100kHz, the core loss is reduced by more than 60% compared to traditional ferrite, while the saturation magnetic density is increased by approximately 30%, allowing the transformer to reduce its volume by 20% to 30% under the same power. This technological breakthrough directly responds to the urgent needs of photovoltaic inverters, DC charging stations, and energy storage converters for high efficiency, high power density, and good heat dissipation performance.
The high-frequency transformer using new magnetic core materials has an overall efficiency that consistently exceeds 98.5%. Some optimized design models can even reach over 99%, far superior to the approximately 96% of traditional solutions. This means that in a 100-kilowatt energy storage system, just the transformer alone can reduce energy loss by several hundred kilowatt-hours each year, significantly lowering the total life cycle cost. At the same time, the high magnetic permeability and low coercivity characteristics of amorphous and nanocrystalline materials enable the transformer to significantly reduce losses under light load and no-load conditions, making it particularly suitable for new energy scenarios with highly fluctuating output power such as photovoltaic power generation.
To meet the stringent requirements of the overseas market for energy-efficient products, Guangdong Haoli Electronics Co., Ltd. fully supports OEM customization services, covering the entire power range from 5W auxiliary power supplies to 50kW high-power inverters. Based on the electrical parameters, installation dimensions and working environment provided by the customers, they can flexibly choose the core material, winding structure and insulation system, and provide complete international certifications such as UL, CE, RoHS, and REACH.
In terms of rapid response, the leading factory has introduced fully automated winding equipment, vacuum sealing production lines and online testing systems, reducing the delivery time of custom samples to 5 to 7 working days. At the same time, it supports the completion of preliminary quotations and technical solution confirmation within 48 hours.
