The high-power IGBT tube is the core capability of the constant frequency soft-switching inverter. How can a manufacturer of high-power IGBT tubes be selected to have products suitable for constant frequency soft-switching inverters?
Today, the high-power IGBT tube market often encounters problems such as efficiency reduction, electromagnetic interference, and shortened product life, which not only affect the normal operation of constant frequency soft-switching inverters but also lead to maintenance costs. For this reason, it is extremely important to seek higher quality substitute models for high-power IGBT tubes.
When electronic designers of constant frequency soft-switching inverters replace the Fairchild FGH75N65SHDT high-power IGBT tube, they need to focus on several key conditions. First, the performance parameters of the high-power IGBT tube are extremely critical, such as whether the rated current can reach 75A and whether the rated voltage can reach 650V. These parameters are closely related to the device's working efficiency. Furthermore, the gate threshold voltage (VGE(th)) and the fast recovery of the reverse parallel connection are also priority factors, with advanced gate threshold voltage (VGE(th)) performance enhancing the quality of the constant frequency soft-switching inverter.
The FHA75T65A has been chosen by many domestic manufacturers of constant frequency soft-switching inverters to replace the Fairchild FGH75N65SHDT and has gained widespread use. We recommend you carefully check its detailed product specifications:
The FHA75T65A is a trench gate field-stop type IGBT with a rating of 75A and 650V, VCEsat typical value: 1.75V-typ, <2.0V, ID (Tc=100℃): 75A; BVCES: 650V; IF (A) (Tc=25℃): 150A; IF (A) (Tc=100℃): 75A.
Moreover, the FHA75T65A model IGBT not only has excellent Vcesat saturation voltage characteristics but also features Trench Field Stop II technology and low switching losses.
