Instantly blocks drive pulses and cuts off the power loop in case of short circuit, over-current, under-voltage and over-temperature abnormalities to avoid module burnout and equipment explosion.
- High-voltage Isolation Protection: Completely isolates the weak-current main control system from the strong-current power main loop, blocking high-voltage impact and electromagnetic crosstalk to ensure stable operation of the low-voltage main control system.

- Fault Self-checking and Tracing: Real-time fault detection and signal feedback accurately report power unit fault types, facilitating rapid troubleshooting and shortening equipment maintenance downtime.
IV. Working Principle
The assembly consists of two layers: the weak-current drive control layer (AGDR-71C) and the strong-current power conversion layer (FS450R17KE3), cooperating to complete variable frequency power conversion.
The equipment main control system outputs low-voltage PWM speed regulation pulse signals to the AGDR-71C drive board. The drive board first electrically isolates the weak signals to avoid high-voltage crosstalk risks, then amplifies the signal power and outputs stable ±15V standard drive voltage to precisely control the turn-on and turn-off of the FS450R17KE3 IGBT module.
The FS450R17KE3 module performs high-speed switching according to drive pulse commands, completes rectification and inversion of main loop power, and converts power frequency AC power into adjustable frequency and voltage variable frequency power to drive high-power load equipment.
During full operation, the AGDR-71C drive board collects real-time working current, drive voltage and status signals of the IGBT module. Once faults such as short circuit, over-current, under-voltage and abnormal overheating are detected, it instantly blocks output pulses, forcibly turns off the IGBT, uploads fault codes to the main control system, and triggers system alarm or interlock shutdown to realize overload protection of power units and the whole equipment.
