Main Functions

1. Optical‑fiber signal receiving & gate signal amplification：Receive PWM trigger instructions transmitted by optical fiber from main controller, convert optical signal into powerful gate drive voltage/current signal, drive IGBT or IGCT power components to realize excitation current adjustment. Optical fiber transmission completely eliminates electromagnetic interference in high‑power cabinet environment.
2. High‑speed hardware fault monitoring：Real‑time monitor power device VCE saturation voltage, detect short‑circuit, over‑current, gate drive power undervoltage fault. When fault occurs, execute μs‑level soft turn‑off to avoid power device damage.
3. Fault signal feedback upload：Convert detected fault status into optical‑fiber / parallel digital signal and send back to main CPU board; fault code can be displayed on local HMI and remote DCS alarm system.
4. On‑board multi‑LED status indication
   • Green LED：Board power supply normal
   • Yellow LED：Fiber signal input valid, drive output active
   • Red LED：Power device fault / drive circuit failure
5. Galvanic isolation function：Realize electrical isolation between low‑voltage control circuit and high‑voltage power circuit, prevent power‑side high‑voltage from penetrating into control board to protect controller hardware and personal safety.
6. Suppression of misleading‑turn‑on：Apply negative bias voltage when power device is off, effectively restrain misleading‑turn‑on caused by high‑voltage dv/dt interference in power cabinet.

Installation & Wiring Requirements

1. Insert board into standard Euro‑card cabinet slot, lock front‑panel handles; ensure back‑plane gold‑finger connector fully contact. Hot‑swap is forbidden, cut off cabinet power before plug‑in or removal.
2. Keep good cabinet ventilation; the board is close to high‑power heating components, pay attention to heat dissipation, avoid conductive dust and corrosive gas accumulation.
3. Optical fiber laying shall avoid sharp bending, minimum bending radius ≥30 mm; separate optical fiber cable from high‑voltage power cable.
4. Strictly separate gate‑drive power wiring, fiber signal wiring and high‑power main‑circuit wiring, lay in different wiring ducts to reduce interference coupling.
5. Cabinet protective grounding must strictly follow excitation system grounding specification, ensure isolation performance and anti‑interference capability.
6. Check 24 V DC logic power supply within allowable tolerance range; over‑voltage will cause permanent damage to gate drive circuit.
