The core function of the fixed-frequency soft-switching inverter is the high-voltage IGBT, which can directly affect its control capability. What method should be used to select a high-voltage IGBT to enjoy products suitable for fixed-frequency soft-switching inverters?

On June 19, 2022, the high-voltage IGBT manufacturer of Feihong Semiconductor received a consultation from Ms. Hui from Heilongjiang.

According to her description, 75A and 650V parameters are the points of attention for manufacturers of fixed-frequency soft-switching inverters when looking for domestic high-voltage IGBT replacement manufacturers. They hope to find a high-voltage IGBT manufacturer with excellent quality.

Thus, Ms. Hui consulted the high-voltage IGBT manufacturer of Feihong Semiconductor hoping they could provide a domestic high-voltage IGBT solution suitable for fixed-frequency soft-switching inverters and replace the FGH75N65SHDT IGBT model.

After understanding the situation, the high-voltage IGBT manufacturer of Feihong Semiconductor immediately arranged a team to rely on the circuit requirements of Ms. Hui's fixed-frequency soft-switching inverter.

They discussed an appropriate and suitable domestic high-voltage IGBT for fixed-frequency soft-switching inverters. Combined with the situation of Ms. Hui from Heilongjiang, it was recommended to use the FHA75T65A IGBT model instead of the FGH75N65SHDT IGBT model for the fixed-frequency soft-switching inverter circuit.

Why is the FHA75T65A IGBT model?

Because the FHA75T65A IGBT model not only has the Trench-FS technology characteristics but also has excellent Vcesat saturation voltage drop, TrenchFieldStopIItechnology, and other advantages.

Moreover, the FHA75T65A model has current and voltage parameter characteristics of 75A and 650V. This characteristic high-voltage IGBT is very suitable for use in fixed-frequency soft-switching inverters.

Importantly, the customer highly recognizes the FHA75T65A high-voltage IGBT model, a famous high-voltage IGBT all-star product!

Of course, as a recommended designer of fixed-frequency soft-switching inverter circuits, you should know the detailed parameters of this FHA75T65A domestic high-voltage IGBT:

The FHA75T65A is a field N-channel trench gate turn-off type with 75A, 650V, typical VCEsat value: 1.75V-typ, <2.0V, ID (Tc=100℃): 75A; BVCES: 650V; IF(A)(Tc=25℃): 150A; IF(A)(Tc=100℃): 75A.

Finally, the high-voltage IGBT manufacturer of Heilongjiang Feihong Semiconductor successfully delivered the high-voltage IGBT supply responsibilities to Ms. Hui.

After testing, Ms. Hui explained the reason for choosing Feihong Semiconductor:

She hopes to improve the conversion current capability of the fixed-frequency soft-switching inverter. Feihong Semiconductor solved her needs, so she chose the FHA75T65A IGBT model.

Feihong Semiconductor provides a service of direct sales by high-voltage IGBT manufacturers, solving the required high-voltage IGBT for fixed-frequency soft-switching inverters. Moreover, the price of domestic high-voltage IGBTs is reasonable.

Ms. Hui said that the IGBT strategy provided by Feihong Semiconductor made her feel comfortable and at ease. Moreover, the service attitude is enthusiastic and generous. She will continue to purchase the FHA75T65A high-voltage IGBT in the future.

The fixed-frequency soft-switching inverter manufacturer chooses Feihong Semiconductor's high-voltage IGBT manufacturer to fully provide strong component supply guarantees for electronic manufacturers such as inverters and portable emergency energy storage power supplies.
