Product Overview

The 029.144.463 is a dedicated Eurocard-format control PCB designed for Alstom Converteam high-power variable frequency converters and DC drive systems used in heavy industrial and railway traction applications. It serves as the core signal processing and closed-loop regulation board, responsible for collecting real-time voltage, current and temperature feedback signals from the power unit, executing vector control algorithms, and outputting isolated PWM trigger pulses to drive thyristor or IGBT power modules.
