The core feature of the sewing machine inverter is the high-voltage IGBT, which can directly affect its durability. Through what channels should one select a high-voltage IGBT that is suitable for the circuit of the sewing machine inverter?

On February 19, 2023, the high-voltage IGBT company of Feihong Semiconductor received an inquiry from Ms. He, a woman from Xinyang, Henan Province.

According to her description, Technical Staff He expected to find a domestic high-voltage IGBT company providing the FHF20T60A high-voltage IGBT model for use in the sewing machine inverter, achieving the domestic replacement of IGBTs.

Thus, she consulted the Feihong high-voltage IGBT company to provide a domestic high-voltage IGBT solution suitable for the sewing machine inverter and capable of replacing the NCE20TD60BF IGBT model domestically.

After understanding the situation, Feihong Semiconductor immediately assigned a team to plan a suitable domestic high-voltage IGBT based on Ms. He's requirements for the sewing machine inverter circuit.

Taking into account Ms. He's actual circumstances, it was recommended to use the FHF20T60A domestic alternative to the NCE20TD60BF IGBT model for the sewing machine inverter circuit.

Why is the FHF20T60A IGBT model chosen?

Because the FHF20T60A IGBT model not only has positive temperature coefficient characteristics but also features short tail current and other advantages.

Moreover, the FHF20T60A model has a current/voltage parameter characteristic of 20A/650V, making this high-voltage IGBT very suitable for use in sewing machine inverters.

Importantly, the high-voltage IGBT provides stable control in sewing machine inverters and has excellent quality!

Of course, as a circuit technician for sewing machine inverters, it is necessary to understand the detailed parameters of this FHF20T60A domestic high-voltage IGBT:

FHF20T60A is a channel N trench gate cutoff type with 20A, 650V, VCEsat typical value: 1.49V, <1.7V, ID (Tc=100℃): 20A; BVCES: 650V; IF(A)(Tc=25℃): 20A; IF(A)(Tc=100℃): 10A.

Ultimately, Xinyang Feihong Semiconductor successfully met Ms. He's high-voltage IGBT supply needs.

After the trial, Ms. He explained the reasons for choosing Feihong Semiconductor:

To enhance the power switch capability of the sewing machine inverter, Feihong Semiconductor addressed her needs, so she chose the FHF20T60A IGBT model.

Feihong Semiconductor provides original equipment manufacturer sales services for high-voltage IGBTs, solving the required high-voltage IGBTs for sewing machine inverters. Moreover, the quotations for domestic high-voltage IGBTs are reasonable.

Ms. He expressed that Feihong Semiconductor demonstrated enthusiasm and generosity in customizing high-voltage IGBTs. She hopes they maintain their初心 (original intention) and provide high-quality parameters for the FHF20T60A model.

The domestic FHF20T60A model can be used in sewing machine inverters. Feihong Semiconductor strives to provide component supply guarantees to electronic manufacturers such as single-ended inverters and standby UPS systems.
