What is Hybrid Active Technology?

Traditional DC-link systems rely on a combination of large inductors and capacitors to control current ripple and stabilize voltage. This requires bulky passive components that work independently, resulting in systems that:

  • limit power density

  • increase material usage

  • constrain overall system optimization

Hybrid active technology replaces this approach by combining:

  • a reduced physical inductor

  • a reduced physical capacitor

  • power electronics

  • coordinated real-time control

Hybrid active systems combine active magnetics and active capacitance into a unified platform for controlling both current and voltage in power electronic systems. This approach replaces conventional DC-link designs based on large passive components with an integrated, intelligent system.

By coordinating current and voltage control in real time, hybrid systems significantly reduce the need for inductance and capacitance while improving overall system stability, efficiency, and power density.

Technical foundation

Beyond Passive – System-Level Intelligence

Hybrid systems introduce a new capability:

multi-domain optimization

  • current dynamics

  • voltage stability

  • harmonic suppression

All are controlled simultaneously.

Impact

  • Adaptive filtering

  • Reduced component stress

  • Improved efficiency under real-world conditions

This represents a shift from component optimization to system optimization

Hybrid systems integrate both Active Magnetics and Active Capacitors into a unified control architecture.
