Alternating current (AC) drives have become indispensable for precise motor control, energy efficiency, and system integration in both industrial and automotive sectors. By converting electrical power into controlled motion, they enhance productivity, reduce operating costs, and support the push toward sustainability.

What Is an AC Drive and Why Does It Matter?

An AC drive—also known as a variable frequency drive (VFD) or inverter—is an electronic device that converts fixed-frequency AC power into a variable-frequency output. This enables:

  • Speed control: Matching motor speed to load requirements
  • Energy savings: Minimizing waste by avoiding full-speed operation when not needed
  • Soft starting: Reducing mechanical stress and inrush currents

Key takeaway: AC drives deliver precise motor management and significant energy reductions, driving both performance and sustainability.

What Are the Key Innovations in ABB’s ACS8080 Medium-Voltage Drive?

ABB’s ACS8080, launched on November 19, 2024, pushes drive technology further by combining proven reliability with advanced digital capabilities.

ABB’s ACS8080 medium-voltage drive delivers up to 98 % converter efficiency, maximizing system performance and energy savings. Its MP3C motor control technology reduces harmonic distortion by around 50 %, extending equipment lifetime and lowering energy losses. Troubleshooting is up to ten times faster thanks to advanced condition-monitoring and diagnostic tools, accelerating failure detection and minimizing downtime. The modular design, with external transformer and sine-filter options, simplifies integration, retrofit, and configuration across diverse applications. Integration with the Crealizer™ software platform enables rapid development of application-specific functions directly within the drive. Finally, accelerated lifetime tests simulating twenty years of operation validate the drive’s reliability under extreme conditions.

Section summary: ABB’s ACS8080 offers nearly 98 % efficiency, half the harmonic distortion, and ten-fold faster diagnostics, ensuring reliable, adaptable, and future-ready medium-voltage drive solutions.

How Does Porsche Engineering’s Modular Multilevel Inverter Generate AC Directly from DC?

In March 2025, Porsche Engineering unveiled a feasibility-study concept called the “AC battery,” merging multiple functions—battery management, pulse inverter, DC-DC conversion, and AC charging—into a single modular unit.

  • Eighteen battery modules over three phases: Each module is individually switch-controlled to form a Modular Multilevel Series Parallel Converter (MMSPC).
  • Direct AC generation: The MMSPC dynamically models the voltage curve to produce sinusoidal three-phase AC from DC without a traditional inverter stage.
  • Dual functionality: Enables direct traction motor control and AC-grid charging through the same hardware platform.

Section summary: Porsche’s MMSPC approach simplifies powertrain architectures by producing AC directly from distributed DC modules, paving the way for more compact, efficient electric vehicles.

What Benefits Do Modular Multilevel Converters Offer?

Modular multilevel designs such as Porsche’s AC battery concept deliver multiple advantages:

  • Scalability: Easy adaptation to various drivetrain variants and power levels
  • Enhanced safety: In the event of a module fault, the system bypasses the affected module and supports a limp-home mode
  • Fast charging potential: Pulsed charging capabilities can significantly reduce charge times
  • Serviceability: Modules revert to independent operation during maintenance or accidents, improving diagnostics and safety

Section summary: Modular multilevel converters boost flexibility, safety, and charging performance, helping future EVs meet evolving consumer and regulatory demands.

Next Steps: Actionable Takeaways

  1. Evaluate drive efficiency: Benchmark current drives against 98 % efficiency standards to identify upgrade opportunities.
  2. Assess condition-monitoring needs: Implement advanced diagnostics platforms similar to ABB’s Crealizer™ integration.
  3. Explore modular designs: Consider modular converter concepts for new EV or industrial applications to improve scalability and serviceability.
  4. Plan for integration: Ensure digital connectivity via edge gateways or cloud interfaces for real-time data access.
  5. Prototype and test: Leverage feasibility-study approaches—like Porsche’s AC battery—to validate novel drive concepts before large-scale deployment.

By understanding and adopting these next-generation AC drive technologies, organizations can unlock higher performance, lower costs, and a clear path toward sustainable operations.
