In the continuous upgrading of market principles, how can offline UPS seize the leading position in actual operation? The main focus is on how to choose a purely domestic alternative model of IGBT for FGH40N60SFD from Fairchild to be used in offline UPS circuits. The quality problems of high-power IGBTs, such as heat dissipation issues, electromagnetic noise, and weak reliability, may affect the reliable operation of offline UPS systems. Therefore, finding a very high-quality domestic alternative product for high-power IGBTs is crucial. In the electronic engineering of offline UPS systems, the selection of the Fairchild FGH40N60SFD high-power IGBT requires engineers to focus on its performance indicators. For example, whether the current can meet 40A, and whether the voltage can reach 600V, etc., these indicators are related to the device's work efficiency. FHA40T65A has already replaced FGH40N60SFD in many international offline UPS production companies and has been widely adopted. It is recommended that you carefully review its detailed product specifications: 1. Circuit current 40A, voltage 600V 2. N-channel trench gate turn-off type 3. VCEsat typical value: 1.51V, <1.85V 4. Equipped with reverse parallel fast recovery diode 5. Low VCEsat, etc. In order to improve the conversion current efficiency of offline UPS circuits, Hongf Semiconductor released the FHA40T65A high-power IGBT. With excellent parameters of 40A and 600V, it can easily solve problems such as product heat dissipation, electromagnetic noise, and weak reliability. Hongf Semiconductor focuses on people-oriented customizations for high-power IGBTs, providing high-quality parameters for the FHA40T65A model. It can provide the most suitable component supply guarantee for offline UPS and fixed-frequency hard-switching inverters.
