1.Main Functions

1. Fiber‑optic galvanic isolation communication between control unit and power cells Multiple fiber‑optic transceiver channels are integrated on the board. It realizes high‑speed optical signal transmission between the main control CPU and cascaded high‑voltage power cells. Optical isolation completely separates low‑voltage control circuits from high‑voltage power potential, effectively suppressing high‑voltage electromagnetic interference, common‑mode noise and surge disturbance inside the medium‑voltage drive system. www.plcva.com
2. Power cell gate drive command forwarding & cell status feedback processing Receive PWM firing pulse commands from the main controller via back‑plane bus, convert electrical signals into optical signals and distribute trigger instructions to each high‑voltage power cell. Meanwhile, receive optical feedback signals of cell operating status, fault flags, temperature and voltage feedback from each power cell, convert optical signals back to electrical signals and upload them to the main control unit for real‑time analysis.

1. High‑voltage interface signal conditioning and signal conversion Process analog and digital feedback signals collected from high‑voltage side, including DC‑link voltage, cell temperature, output voltage and current sampling signals. Complete signal filtering, level conversion and signal buffering, transmit conditioned valid measurement data to drive main control logic for closed‑loop motor control and protection calculation.
2. Local hardware self‑diagnosis and fault reporting Real‑time monitoring of fiber channel link status, transceiver health, internal power supply and hardware circuit integrity. Detect fiber breakage, signal loss, channel abnormality and cell communication timeout. Generate fault codes and alarm signals, deliver trip triggers to main control logic when critical communication failures occur, to protect power units and the whole medium‑voltage drive equipment.
3. Back‑plane bus and peripheral interface expansion Equipped with internal high‑speed back‑plane connectors for data exchange with MV580 main CPU board. Reserve multi‑channel digital I/O interfaces for interlock coordination with other sub‑boards inside the drive cabinet. Support parameter interaction, status data exchange and fault log transmission inside the complete drive system.More products: www.plcva.com
4. Auxiliary power management for on‑board circuits Accept internal 24 VDC auxiliary power supply from the drive cabinet, generate multiple stabilized power rails for on‑board FPGA chip, fiber transceivers and signal processing circuits, ensuring stable operation under industrial temperature fluctuation conditions.
