Core Features
- Centralized signal coordination: Collect multi‑point feedback signals from power units, voltage and current sensors inside the medium‑voltage drive, distribute timing and trigger commands for IGCT power devices.
- Comprehensive hardware protection: Integrates over‑voltage, over‑current, over‑temperature and short‑circuit detection logic; triggers rapid system shutdown to protect power semiconductors once fault occurs.
- Industrial conformal‑coated PCB: Anti‑dust, anti‑humidity and anti‑corrosion coating adapts to heavy‑duty workshop environment, improves long‑term operational stability.
- Plug‑in rack‑mount design: Convenient for on‑site replacement, reduces drive downtime during maintenance.
- High‑voltage isolation design: Reinforced isolation between low‑voltage control circuit and high‑voltage power circuit to enhance operator and equipment safety.
- Fault diagnosis capability: Captures drive running status and fault codes, transmits diagnostic data to main control unit for troubleshooting.
Main Functions
- Receive operation commands from the main drive controller, generate and distribute synchronized trigger signals for IGCT power modules.
- Acquire real‑time analog & digital feedback signals including bus voltage, output current, power unit temperature.
- Execute multi‑level hardware and software protection for the medium‑voltage converter system.
- Realize internal high‑speed data exchange between different functional boards inside the drive cabinet.
- Record fault events and status parameters, support drive fault diagnosis and post‑failure analysis.
- Work cooperatively with other power and interface boards to complete closed‑loop speed & torque regulation for high‑power AC motors.
