GE DS200MBHAG2A Multi-Bridge Link Interface Card

The card’s function is a cornerstone of advanced power conversion and control:

  • Multi-Bridge Control: In high-power applications, a single power converter bridge (e.g., a 6-pulse rectifier) is often insufficient to handle the required voltage or current and can introduce significant harmonic distortion. A multi-bridge system (e.g., a 12-pulse or 24-pulse configuration) uses two or more bridges connected in series or parallel. The DS200MBHAG2A is specifically designed to manage these complex configurations.
  • Link Interface: This card acts as the central coordinator. It receives a single, unified control command from the main processor (like a DSPC card) and translates it into precisely timed, synchronized firing signals for each individual power bridge. This synchronization is crucial to ensure the bridges operate in perfect harmony.
  • Harmonic Reduction: One of the main benefits of a multi-bridge system is its ability to significantly reduce harmonic currents and voltages on the AC power line. By precisely staggering the switching of the multiple bridges, the DS200MBHAG2A helps to create a smoother, cleaner waveform, which improves power quality and reduces stress on the electrical grid.
