Due to their different frequency characteristics, medium-frequency DC inverter transformers and high-frequency DC inverter transformers are suitable for industrial heating, medical equipment, new energy, and communications fields, respectively78. This article analyzes the advantages and disadvantages of the two in terms of efficiency, anti-interference, load adaptability, and cost, and provides a technical basis for selection.

Medium frequency DC transformers are efficient, compact, low harmonic, and suitable for new energy, industry, and transportation. They empower the future of green energy with high-frequency devices and innovative control.

Resistance welding transformers have high welding efficiency, fast speed, strong weldment, and reduce welding costs. They are suitable for welding a variety of materials, such as aluminum alloys and aluminum and other materials with fast thermal conductivity and poor weldability. In addition, for the welding of galvanized sheets and ordinary multi-layer sheets, welding transformer's welding quality is also much higher than that of power frequency welding machines.
