/// Power Electronics and Inverter

SciMo’s inverter technology is based on years of experience and optimization. Application-oriented development in the field of electric motors has resulted in a both powerful and reliable platform. The inverters are optimized for operation with SciMo-motors, but can also be adapted to drive any motor system.


/// Inverters

SciMo is producing power electronic hardware based on SiC-MOSFET- and Si-IGBT-modules. All our inverters are optimized for highest power density and a DC voltage of 800V.

Complementing our portfolio, we develop custom inverters fast and efficiently. Due to our in-house prototype manufacturing and slim design processes and we are also able to offer a competitive, great value.

/// Applications

SciMo has a deep knowledge in power electronics to enable the full performance of our advanced motor technology. This contains advanced controller technology using a non-linear predictive control algorithm for highly dynamic torque control, highly dynamic speed control as well as sensor fault-detection during runtime. Our inverters are used in a variety of applications. A short overview can be found in the motor section. 

If you are looking for an inverter for other applications just contact us.

/// Inverter Technology

SciMo uses advanced manufacturing technologies in its own production center to give the inverter systems the best characteristics in terms of power density and functionality.


/// Control Technology

We are experts in the field of control of electric drive systems. Depending on the application, we rely on a reasonable combination of modern and conventional control algorithms.

When developing new concepts or customizing the control system, we achieve short development times by directly implementing the algorithms on our own rapid prototyping platform. New algorithms are tested directly on our engine test benches. With the help of our real-time monitoring software, we can parameterize the controllers directly on the test bench or subsequently optimize them offline using the measurement data from the test bench.

We use modern control algorithms such as:

  • Non-linear predictive control
  • Optimal control
  • Load torque observer
  • Robust sensorless control
  • Efficiency-optimized control 
This also creates the possibility of highly dynamic control of drive systems with different requirements, such as:
  • Highly dynamic torque control 
  • Highly dynamic speed control
  • Sensor fault-detection during operation
  • Sensorless control during fault-condition

Due to many years of experience in the fields of control engineering and drive systems we are the perfect partner for developing or improving your drive control system. 


/// Lightweight construction

The aluminum lightweight housings of the inverter systems achieve the necessary robustness and a protection class of IP67 with minimum weight due to their optimized design.


/// Innovative cooling concepts

Just as with the motors, the performance of the inverter system can be increased by improving the cooling of the power semiconductors. For this reason, SciMo focuses on innovative cooling concepts such as the manufacturing of high-performance cooling channel systems by the friction stir welding process or the direct water cooling of module cold plates. The sophisticated machining of the cooling plates and the complex fluid control systems are manufactured in-house.


/// Overview of power electronics

The following list shows some examples of inverters developed by us with performance specifications. We do not display customer-specific developed inverters.

All inverters feature a cooling loop which is directly integrated into the housing, resulting in an optimal thermal transition coefficient between coolant and modules. A water/glycol mixture is used as coolant.


/// ISC1 12-50-IC

The ISC1 12-50-IC inverter is our most compact inverter and is based on fast switching SiC-MOSFET modules. This technology enables rapid control loops without a compromise in system efficiency.
