Engineering

Maskinel provides engineering services across modern power electronics and control systems, spanning the full development and measurement chain, from component selection through control design to system optimization.

Advanced Control Theory

We implement advanced control theory on microcontrollers and FPGA platforms, developing the control algorithms that hold performance and stability in complex power systems.

That work includes real-time control with high precision and fast response times, running on dedicated hardware platforms for maximum reliability.

Semiconductor Technologies

GaN MOSFET Gallium nitride switching circuits at the highest efficiency and switching frequency.

SiC MOSFET Silicon carbide circuits with high efficiency and switching frequency.

Si IGBT Proven IGBT topologies for high-power applications, focused on loss minimization and thermal management.

Advanced Topologies

Solid State Transformer Intelligent transformers with integrated power conversion and smart grid functionality.

T-type Inverters Three-level, three-phase topology for reduced harmonic content and improved efficiency.

Multilevel Converters Advanced topologies for high-power and medium-voltage applications.

Simulation and Modeling

Simulation carries system analysis and optimization long before hardware exists.

LTSpice Detailed circuit simulation and component characterization.

MATLAB/Simulink Modeling at system level and control design for PID and state space controllers.

PLECS Specialized power electronics simulation for switching and efficiency analysis.

We focus in particular on grid integration, THD(i), common-mode noise analysis and EMC optimization. Advanced filter calculations keep systems compliant with international standards.

Industrial Automation & Control

We implement automation on industrial PC platforms such as Beckhoff, programming object-oriented C/C++ and Python to UML and SysML design principles.

Everything is coded in a single program, which issues the system commands through the ADS layer (Automation Device Specification). Safety circuits run directly on the PLC, executing separately on their own core. Because the core of the code is plain C/C++ and Python, moving to a different PLC supplier stays straightforward.

Integrating industrial protocols keeps commissioning fast and makes subsystems easy to add. We build universal interfaces, so interoperability and scalability hold in complex industrial environments, whether the plant is a hydrogen system, a solar park or another industrial process.
