IGBT can convert the DC power from the inverter circuit of the inverter welder into AC power with a frequency of several tens of kHz, and then after the main transformer steps down the voltage, it is rectified and filtered to obtain a stable DC output welding current, greatly improving the function of the welder while reducing its size and weight and significantly reducing energy loss.

Based on this principle, for domestic welder manufacturers, selecting a high-quality IGBT for use in the welder circuit is essential. Are there any recommended IGBT single tubes specifically for welders?

For Feihong Semiconductor, which specializes in solving problems related to electronic components for domestic electronics manufacturers, this is a trivial issue. For products in different scenarios, Feihong Semiconductor will arrange dedicated product engineers to solve batch sampling issues.

For example, after testing, Feihong Semiconductor recommends that welder manufacturers prioritize using these two IGBT single tube models: FHA60T65A and FHA40T65A.

Why are these two products recommended?

Because they both have: high reliability, with reverse parallel fast recovery diodes, Trench Field Stop Ⅱ technology (short tail current, excellent Vcesat saturation voltage drop, low turn-off loss), and possess positive temperature coefficient.

The above product features are very suitable for application in welder circuits, as all welders hope to improve the efficiency and welding effect of their products fundamentally.

In addition to the above effects, these two IGBT single tubes can replace parameters of various domestic and international IGBTs for use. Today, we recommend to welder manufacturers the applications of these two products and the IGBT products they can replace for use in welders.

The FHA60T65A model IGBT single tube can replace FGH60N60SMD, and the FHA40T65A model IGBT single tube can replace Fairchild's FGH40N60SFD specifically for welders. In the welder circuit, 4 IGBTs form a full bridge. Depending on the power demand, some solutions will parallel them to increase power adaptability, starting with quantities that are multiples of 2.

Recommended IGBT for welders: FHA60T65A and FHA40T65A not only have suitable parameters but also offer excellent product testing services provided by Feihong Semiconductor's engineers.
