Matrixumrichter U1000

Yaskawa U1000 – Low Harmonics Regenerative Matrix Converter
The Yaskawa U1000 is a top-of-the-line frequency inverter based on innovative matrix converter technology. As a direct AC-to-AC converter without a DC bus, it combines three functions in one compact unit: standard drive, harmonic filter, and regenerative unit – with no external components required.
Clean Power Quality
Thanks to sinusoidal input currents, the U1000 achieves a total harmonic distortion of THDi < 5 % (IEEE 519 compliant) at a power factor of 0.98. This significantly reduces stress on transformers, generators, and cables – eliminating the need for oversizing.
Full Power Regeneration
Braking energy is fed directly back into the grid and made available to other consumers in the building. Braking resistors that waste energy as heat become entirely unnecessary, significantly reducing fire risk, cooling requirements, and operating costs.
Compact Footprint
Compared to conventional solutions with separate regenerative units and harmonic filters, the U1000 saves up to 50 % of cabinet space. Connection principle: 3 wires in, 3 wires out – nothing more required.
Built-in Functional Safety
Integrated SIL3/PLe STO input (TÜV-certified) without external wiring. All common fieldbus systems (PROFINET, EtherCAT, Ethernet/IP and others) are supported via option cards.
Maintenance-Free & Long-Lasting
The capacitor-free design is engineered for 10 years of maintenance-free continuous operation. Four international awards in Japan, Europe, and the USA confirm the technological uniqueness of this product.
