Ungrounded UPS senior management urgently needs a device that can effectively control and regulate current —— high-power IGBT tubes. Selecting a first-class domestic high-power IGBT tube device to replace the FGH60N60SMD model is very important in the design of ungrounded UPS circuits. At present, the high-power IGBT tube market often has the following shortcomings in poor-quality high-power IGBT tubes: low reliability, efficiency reduction, poor heat dissipation, etc. These shortcomings not only seriously damage the normal operation of ungrounded UPS equipment but also lead to maintenance costs. Therefore, finding an extremely high-quality replacement high-power IGBT tube product is very important. When ungrounded UPS technicians replace the FGH60N60SMD high-power IGBT tube model, they need to focus on several key parameters. First, the performance parameters of high-power IGBT tubes are extremely urgent, such as whether the rated current can reach 60 amperes, whether the rated voltage can reach 650 volts, etc. These parameters are related to the device's work efficiency. It should be noted that thermal resistance (Rth(j-c)) and high reliability are also key points. Excellent thermal resistance (Rth(j-c)) performance can enhance the quality of ungrounded UPS. Many international ungrounded UPS manufacturers have previously used FHA60T65A as a replacement for FGH60N60SMD and have been widely adopted. It is recommended that everyone fully understand its performance parameters: 1. High reliability 2. Circuit and voltage with 60 amperes and 650 volts 3. VCEsat typical value: 1.75V-typ, <2.0V 4. Trench gate field stop type IGBT 5. Equipped with a fast recovery reverse parallel diode, etc. In order to enhance the control capability of ungrounded UPS, Feihong Semiconductor solves Ms. Lan's requirements and selects the FHA60T65A IGBT model. To optimize the control performance of the ungrounded UPS circuit, Feihong Semiconductor strongly recommends selecting the high-power IGBT tube of the FHA60T65A model. This high-power IGBT tube with a rated current of 60 amperes and a rated voltage of 650 volts can effectively solve problems such as low product reliability, reduced efficiency, and poor heat dissipation.
