Combining core performance advantages

1. Efficient collaboration, excellent energy conversion efficiency

FS450R12KE3 adopts ABB’s advanced trench gate IGBT technology, combined with optimized carrier distribution design, to achieve low conduction loss and switching loss; The AGDR-71C effectively suppresses voltage spikes and current oscillations during IGBT switching and reduces switching losses through precise gate voltage control (forward drive voltage+15V, reverse turn off voltage -15V). The synergy between the two enables the energy conversion efficiency of the entire combination to reach over 98%, significantly reducing equipment operating energy consumption and meeting industrial energy-saving requirements.

2. A comprehensive protection mechanism ensures safe and reliable operation

This combination constructs a dual protection system of “module native protection+driver active protection”: FS450R12KE3 has a built-in temperature sensor and overcurrent detection structure, which can provide real-time feedback on the operating status; The AGDR-71C uses DESAT (desaturation) detection technology to quickly identify IGBT short-circuit faults, with a response time of no more than 1 μ s. It also has functions such as gate undervoltage protection and over temperature protection, which can cut off the drive signal at the moment of fault occurrence, avoiding IGBT module burnout and greatly improving the reliability and service life of the entire system.

3. High power density, easy integration

FS450R12KE3 adopts EconoPACK ™ 3 compact packaging forms, achieving 450A/1200V power output within a limited volume; AGDR-71C adopts a modular design, with a compact size and standardized installation hole positions, which can be quickly adapted and assembled with FS450R12KE3. The high power density design of both not only reduces the installation space requirements of the equipment, but also simplifies the system wiring and integration process, improving the efficiency of equipment research and production.

AGDR-71C adopts a dual isolation technology combining optocoupler and magnetic isolation, with an isolation voltage of up to 2.5kVrms, effectively resisting electromagnetic interference (EMI) and common mode noise in industrial sites; FS450R12KE3 reduces electromagnetic radiation during the switching process through optimized packaging structure and parasitic parameter design. The entire combination complies with the IEC 61800-3 electromagnetic compatibility standard and can operate stably in complex electromagnetic environments such as metallurgy, chemical engineering, and mining.

Installation and usage precautions

1. Installation specifications

-Before installation, it is necessary to confirm the model compatibility between FS450R12KE3 and AGDR-71C to ensure that the current and voltage levels of the driver module are compatible with the power module.

-When installing the power module, it is necessary to apply thermal grease and fix it on the heat sink with a torque wrench according to the specified torque (refer to the product manual) to ensure good heat dissipation and avoid excessive junction temperature caused by poor contact.

-The connection cable between the drive module and the power module should use shielded wires, and the wiring should be short and straight to reduce parasitic inductance and avoid voltage spikes during the switching process.

-The installation environment should be kept dry, ventilated, and free from dust, oil, and corrosive gases. The ambient temperature should not exceed the rated working range of the module.

2. Debugging and maintenance

-Before debugging, it is necessary to check whether the power supply voltage (± 15V) of AGDR-71C is stable and whether the input control signal is normal, in order to avoid module damage caused by abnormal power supply.

-During the first operation, it is necessary to monitor the junction temperature and temperature rise of the IGBT module to ensure that the cooling system (such as cooling fans and water cooling devices) is working properly and the junction temperature does not exceed 120 ℃ (recommended value).

-Regularly (recommended every 6 months) check the tightness of module connection bolts, the aging of thermal conductive silicone grease, and the insulation performance of cables, and replace aging components in a timely manner.

-If the system malfunctions, it is necessary to first locate the fault type through the fault feedback signal of AGDR-71C, and then restart after troubleshooting to avoid blind closing and causing secondary faults.
