As a expert of soft magnetic core, Coilcore make high frequency nanocrystalline core to replace old ferrite core, which used in inverter, welder machine.  What's more, we can copper winding the cores of transformers based on OEM design. We obtain question from customers about the HF Transformers, and feedback professional suggestion like below:

Question: Is it permissible to connect 6 transformers in parallel from the same transformers ?

Coilcore Answer: Inverter welding machine transformers can be connected in parallel to increase the output power, but it is recommended to use transformers with similar inductance values in parallel, otherwise transformers with different inductance values will heat up differently, which will affect the life of the transformer with high heat.

Question: Is it possible to operate the transformer at 5,000 to 20,000 Hz, and what is the permissible range?

Coilcore Answer: The working frequency of the nanocrystalline core transformer can reach ~30KHZ, so the working frequency of 5K~20KHZ is acceptable
