The key feature of an offline UPS is the high-voltage IGBT. How can an offline UPS manufacturer choose a high-voltage IGBT supplier to obtain suitable high-voltage IGBT products for offline UPS applications?

On March 7, 2023, Feihong Semiconductor's high-voltage IGBT manufacturer received an inquiry from Ms. Rui in Guizhou.

According to her description: The circuit diagram of the offline UPS manufacturer previously used the FGH40N60SFD IGBT model. Currently, she hopes to seek domestic high-voltage IGBT manufacturers to supply the FHA40T65A high-voltage IGBT model for use in offline UPS systems as a replacement for the FGH40N60SFD IGBT.

Thus, she consulted Feihong Semiconductor's high-voltage IGBT manufacturer hoping they could provide a suitable domestic high-voltage IGBT solution for offline UPS systems and replace the FGH40N60SFD IGBT.

After understanding the situation, Feihong Semiconductor's high-voltage IGBT manufacturer immediately dispatched a team based on Ms. Rui's offline UPS circuit diagram requirements.

They arranged a proper and suitable domestic high-voltage IGBT for offline UPS systems. Considering Ms. Rui's situation, it was recommended to use the FHA40T65A IGBT instead of the FGH40N60SFD IGBT in the offline UPS circuit diagram.

So, what is the FHA40T65A IGBT model?

Because the FHA40T65A IGBT model not only has reverse parallel fast recovery diode characteristics but also features positive temperature coefficient and very short tail current.

Moreover, the FHA40T65A model has current and voltage parameters of 40A and 600V respectively. These characteristics make this high-voltage IGBT highly suitable for use in offline UPS systems.

Importantly, this high-quality, long-lasting high-voltage IGBT!

Of course, as a technical staff member of the offline UPS circuit diagram, it is necessary to explore the detailed parameters of this domestic high-voltage IGBT, the FHA40T65A:

The FHA40T65A is a trench gate field-stop type IGBT with 40A and 600V, VCEsat typical value: 1.51V, <1.85V, ID (Tc=100℃): 40A; BVCES: 600V; IF(A)(Tc=25℃): 40A; IF(A)(Tc=100℃): 20A.

Ultimately, Guizhou Feihong Semiconductor's high-voltage IGBT manufacturer successfully implemented Ms. Rui's plan for high-voltage IGBT supply.

After testing, Ms. Rui explained her reasons for choosing Feihong Semiconductor:

She hoped to find the FHA40T65A high-voltage IGBT model in Guizhou to enhance the performance of the offline UPS system. Ms. Rui, the responsible person of the Guizhou offline UPS manufacturer, chose Feihong Semiconductor due to its excellent service.

Feihong Semiconductor provides a service for direct sales of high-voltage IGBTs, solving the required high-voltage IGBTs for offline UPS systems, and the prices of domestic high-voltage IGBTs are reasonable.

Ms. Rui mentioned that Feihong Semiconductor's service attitude is meticulous and reassuring, making her feel comfortable entrusting them with the customization of the FHA40T65A high-voltage IGBT model.

Offline UPS manufacturers choose Feihong Semiconductor as their high-voltage IGBT supplier to provide strong component supply guarantees for load-commutated inverters, outdoor mobile power supplies, and other electronic manufacturers.
