Technical Architecture & Functional Positioning
Positioned at the power conversion layer in modular drive topologies, this unit rectifies incoming mains to a stabilized DC bus, distributing power to multiple inverters and controllers via shared bus connections. It enables compact system designs by centralizing rectification, minimizing redundant components compared to distributed supplies.
The architecture employs IGBT-based active front-end rectification with precise voltage regulation, maintaining the DC bus near 700 V through closed-loop control. This non-regenerative design dissipates excess braking energy via optional external resistors, prioritizing simplicity and cost in applications without frequent deceleration. Key technologies include integrated mains filtering for harmonic reduction and module bus communication for status monitoring and coordinated shutdowns. These address challenges like grid compliance in sensitive installations and rapid fault isolation to protect downstream inverters.
Engineering benefits are evident in energy-efficient setups where load profiles favor motoring over generating modes. The stable bus voltage enhances torque consistency across axes, critical for synchronized processes. In retrofit projects, its plug-compatible interfaces reduce integration effort, allowing upgrades to higher power without extensive rewiring.
