Core Functions

Note: This is an auxiliary signal‑conditioning interface module for high‑voltage inverters. It does not generate high‑voltage power output; it processes feedback and interlock signals for the converter system.

1. High‑voltage side signal sampling & isolation conditioning Collects voltage and current feedback signals from medium‑voltage converter power‑cell circuits. Implements galvanic isolation, filtering and signal conditioning, converts high‑voltage measurement signals into low‑voltage level signals that can be recognized by the drive main‑control unit.
2. Cabinet‑level interlock signal processing Processes safety interlock signals from the inverter cabinet: door‑interlock, temperature‑overheat, cooling‑system status and other safety feedback signals. Conditions these discrete signals and sends them to main‑control board for safety‑protection logic judgment.
3. Fault‑signal transmission and status monitoring Transmits abnormal status signals of power‑cell, cooling system and cabinet auxiliary circuits to main‑control unit. Provides hardware‑level fault‑detection circuits for auxiliary circuit failure diagnosis.
4. Electrical isolation and noise suppression Provides galvanic isolation between high‑voltage power circuit side and low‑voltage control circuit side. Suppresses strong electromagnetic interference generated by high‑power converter, protects sensitive control electronics.
5. On‑board status indication On‑board LED indicators show power‑on and fault status for on‑site maintenance troubleshooting.
