Technical Architecture & Functional Positioning
This regenerative infeed unit resides at the power supply layer of modular drive systems, transforming three-phase mains into a controlled DC bus while enabling bidirectional energy flow. It centralizes power for multiple inverters, promoting efficient bus sharing and eliminating separate rectifiers per axis.
The architecture features an active IGBT front-end with sinusoidal current draw and precise voltage control, maintaining the DC bus around 700 V. Regenerative operation feeds excess energy from braking back to the mains, avoiding dissipation and complying with energy efficiency standards. Integrated mains filtering minimizes harmonics, while module bus communication coordinates diagnostics, fault responses, and energy management across the system. These elements tackle grid interference, peak demand charges, and heat buildup in cabinets.
In practice, this design excels in dynamic applications with frequent deceleration, recovering up to significant portions of energy and lowering total consumption. The robust diagnostics isolate issues quickly, enhancing availability in production-critical environments. For expansions or retrofits, its standardized interfaces simplify scaling without major redesigns.
