A drive is more than the sum of its components.
Electrical behavior, thermal conditions, and component interactions can all influence how the final system performs. And discovering an issue after the test hardware is built can be expensive.
Simulation helps accelerating the design process.
By modeling critical parts of the drive before committing to hardware, engineers can compare design options, investigate worst-case scenarios, and reduce costly trial-and-error.

️ AI Needs More Power. Not More Space.
As AI server power supplies move toward ever-higher power densities, the DC link has to keep up without taking up more valuable board space.
That is where capacitor design becomes a system-level consideration.
Our latest ultra-compact snap-in aluminum electrolytic capacitors combine up to 500 V rated voltage with a higher capacitance-to-volume (CV) ratio, giving PSU designers greater flexibility to meet demanding power-density requirements.
More capacitance. Higher voltage. Less volume.

Because Every Component You Remove Makes the System Better.
Designing compact 96 V battery systems isn't only about fitting more power into less space. It's about reducing complexity, improving reliability, and making every cubic centimeter count.
Our latest aluminum electrolytic capacitor portfolio helps engineers do exactly that.
The new 125 V axial and soldering-star capacitors eliminate the need to connect capacitors in series for many 96 V DC-link designs. The result? Simpler capacitor banks, lower assembly effort, fewer components, and robust performance even under demanding thermal and vibration conditions.
Together with the upgraded 63 V series, the portfolio supports applications ranging from micromobility and small xEVs to forklifts, electric boats, industrial electronics, and even humanoid robots.

Taming SiC Starts with What You Can't See
As switching frequencies increase, parasitic inductance becomes a critical design challenge. Even small amounts of ESL can contribute to voltage overshoots, additional stress on power semiconductors, and reduced system reliability.
Our latest MKP DC HF capacitor platform was developed to address exactly these challenges, combining ultra-low inductance with high ripple-current capability for next-generation SiC-based power electronics.

Variable-Speed Drives All Follow The Same Principle. Until Physics In.
At their core, variable-speed drives all do the same thing: they regulate voltage and frequency to operate electric motors efficiently.
The principle is straightforward.
Designing a drive that performs reliably under real operating conditions is not.
As power levels increase, every engineering decision carries more weight.
Input protection.EMI filtering.Power conversion.DC-link stabilization.Current sensing.Output filtering.
Each functional block influences the next.
And ultimately, every design decision shapes the overall performance, efficiency, and reliability of the system.
Because successful drive design isn't about optimizing individual components. It's about engineering an architecture where each building block interact seamlessly.
That's where design confidence begins.
