BOMBARDIER DCC2223A-3EST125-977 – Transit Traction Drive Control Unit | BOMBARDIER Propulsion Platform
Engineering Background
The DCC2223A-3EST125-977 is a purpose-engineered Drive Control Unit (DCU) developed by BOMBARDIER Transportation for deployment in urban rail and light transit propulsion systems. It forms the core intelligence layer of the traction drive chain, translating high-level speed and torque commands into precise IGBT gate-drive signals for the traction inverter.
Product Positioning
Designed for procurement engineers and rolling-stock maintenance teams requiring a direct OEM-equivalent replacement or spare-pool addition. The DCC2223A-3EST125-977 is stocked and verified by Konmask.com as a genuine BOMBARDIER assembly, suitable for both scheduled overhaul programs and emergency line-restoration scenarios.

System Architecture & Signal Flow
The DCC2223A-3EST125-977 sits between the Vehicle Control Unit (VCU) and the traction inverter power stage. It receives torque/speed reference signals via the vehicle bus (MVB/CAN), executes the PWM modulation algorithm, and outputs isolated gate-drive pulses to the IGBT modules. Simultaneously, it monitors DC-link voltage, phase currents, and thermal sensors, feeding real-time status back to the VCU and the onboard diagnostic recorder.
Signal path: VCU → [MVB/CAN] → DCC2223A-3EST125-977 → [Gate Drive] → IGBT Inverter → Traction Motor
