About us

Negal Engineering AG – Engineering that works

Negal Engineering AG stands for the development and implementation of demanding electronic solutions. The focus lies on power electronics, switch-mode power supplies, LED systems, and custom hardware development. Projects are supported from the initial idea through to series production, with a clear focus on quality, functionality, and practical implementation.

The strength of Negal lies not in a single product, but in the ability to understand complex systems. Many projects begin where existing solutions no longer work or reach their limits. This is where structured thinking, technical depth, and practical experience lead to solutions that perform reliably in real-world applications.

System understanding as a foundation

Every development starts with a thorough analysis. The key is not optimizing individual components, but understanding the interaction of the entire system.

Electronics, mechanics, thermal behavior, and EMC influence each other. Optimizing one area in isolation often creates issues elsewhere. That is why a holistic approach is applied from the very beginning.

Decisions made during the concept phase define the success of the project. Using simulation tools and experience, potential risks are identified early and addressed before they become problems.

Power electronics across a wide range

A core area of expertise is power electronics. Solutions are developed for a wide range of applications, from compact designs to complex high-power systems.

This includes:

Switch-mode power supplies across various power levels
Voltage ranges from low voltage to high voltage applications
High current systems
Applications requiring fast and precise control

The focus is always on efficiency, thermal stability, and long-term reliability. A solution is only considered successful when it performs consistently under real operating conditions.

Custom switch-mode power supplies

Standard products often do not meet specific requirements. Therefore, power supplies are designed individually for each application.

Both technical and economic aspects are taken into account. The goal is a solution that is not only functional but also manufacturable.

Typical development steps include:

Topology selection and design
Component dimensioning
Efficiency and loss optimization
Consideration of manufacturing processes
Preparation for series production

This results in robust, reliable, and cost-effective systems.

LED systems and lighting technology

Developing LED systems requires an interdisciplinary approach. Beyond light output, electronics, thermal management, and control systems are essential.

A reliable solution requires precise coordination of all components.

This includes:

LED drivers and control gear
Dimming and control concepts
Interfaces such as DALI
Wireless control solutions
Thermal design and simulation

Thermal management is especially critical for system lifetime. Simulations allow early identification and optimization of critical areas.

EMC integrated from the beginning

Electromagnetic compatibility is essential for market readiness. Addressing EMC too late often leads to delays and additional costs.

Therefore, EMC is integrated directly into the development process:

EMC-compliant circuit design
Optimized PCB layout
Measurements on prototypes
Targeted improvements

The goal is a product that meets all relevant standards without unnecessary iterations.

From idea to series production

Projects follow a structured process:

Concept and analysis
Definition of requirements and system architecture

Development
Circuit design, layout, and prototyping

Validation
Testing, measurement, and optimization

Industrialization
Preparation for manufacturing

Production
Assembly of electronic modules and complete devices

This structured approach ensures efficiency and reliability throughout the project.

Practical engineering approach

The focus is always on real-world application. Decisions are made with the final product and its use in mind.

Key considerations include:

Behavior under continuous operation
Thermal stress on components
Component availability
Assembly and manufacturing effort

These factors are integrated early in the development process.

Collaboration as a key factor

Successful projects are built on clear communication and trust.

Key principles include:

Reliable and transparent communication
Fast coordination
Technical depth in discussions

The goal is a collaboration that is efficient and solution-oriented.

Continuous development and expertise

Technology evolves continuously. Through collaboration with research institutions and partners, knowledge stays up to date.

New approaches are integrated when they provide real value. The focus remains on practical benefit rather than trends.

Typical application areas

Solutions are used in:

Industrial automation
Energy systems
Mechanical engineering
Medical technology
Lighting systems

These applications often require high reliability and long service life.

When challenges become complex

Many projects begin when:

existing solutions fail
requirements are unclear or complex
time pressure exists
high reliability is required

In such cases, a structured approach leads to clear and workable solutions.

Commitment to quality

Every solution follows clear principles:

Technically sound
Reliable in operation
Economically viable
Designed for long-term use

The goal is a product that performs consistently in everyday use.
