The current control circuit of the resistance welding machine can replace the FGH75N65SHDT model with the domestic high-quality IGBT single-pipe FHA75T65A.

Why is this FHA75T65A IGBT single-pipe?

Because the core requirement for the IGBT single-pipe in the resistance welding machine is to provide better current control and efficiency. So why can it achieve this? We need to understand the features of this IGBT single-pipe:

FHA75T65A is an N-channel trench gate turn-off IGBT, using Trench Field Stop technology and optimized processes to achieve extremely low VCEsat saturation voltage drop, and make a good trade-off between conduction loss and switching off loss (Eoff).

For the resistance welding machine, it is recommended to use the FHA75T65A IGBT single-pipe from Feihong Electronics instead of FGH75N65SHDT because it has high reliability and fast recovery diode characteristics in reverse parallel configuration, Trench Field Stop technology (short tail current, low switching off loss, excellent Vcesat saturation voltage), and positive temperature coefficient.

From the above features, it can be known that the parameters of this 75A, 650V current and voltage FHA75T65A model IGBT single-pipe are very suitable for use in the circuit of the resistance welding machine.

In application, our resistance welding machine R&D engineers must understand the detailed parameters of the high-quality FHA75T65A domestic model: It has 75A, 650V, VCEsat typical value: 1.75V-typ, <2.0V; ID (Tc=100℃): 75A; BVdss: 650V; IF (A) (Tc=25℃): 150A; IF (A) (Tc=100℃): 75A.

Currently, the FHA75T65A model IGBT single-pipe has been widely used in resistance welding machines, high-frequency vehicle-mounted sine wave AC220V inverters, 5000W photovoltaic inverters, outdoor energy storage power supplies, UPS, and various soft and hard switching and PFC circuits. It can replace other brand models: FGH75N65SHDT.

The packaging form of FHA75T65A is TO-247, with 75A, 650V, Vcesat-typ (@Ic=75A): 1.75V; IC (A): 75A; Bvces (V): 650V; Vge (±V): 30;.

Resistance welding machines have been widely applied in various scenarios where welding is needed in people's daily lives. Therefore, in addition to selecting the FGH75N65SHDT model, the domestic model FHA75T65A from Feihong Semiconductor can also be used as a replacement to improve product control efficiency in components.
