High-Frequency Transformers for SMPS, DC-DC Converters, and Power Electronics Applications
Introduction
As electronic devices continue moving toward higher power density, compact size, and improved efficiency, high-frequency transformers have become a core component in modern switching power supply systems. Their unique advantages allow systems to maintain output power while significantly reducing size and weight.
From switching power supplies (SMPS) and DC-DC converters to communication equipment, industrial control systems, renewable energy systems, and automotive electronics, high-frequency transformers play a critical role in energy transfer, electrical isolation, and voltage conversion.
What Is a High-Frequency Transformer?
A high-frequency transformer is a magnetic component typically operating above 20 kHz, designed to transfer energy between circuits while providing electrical isolation.
