As the world around us continues to advance, as does our technologies. Whilst this has driven worldwide development, it has also called for the introduction of newer and more efficient technologies, which many businesses have struggled to develop. Since 1995, Negal Engineering has been developing and producing highly efficient power electronics solutions for the industrial and control technology sector. Renowned for its excellence, the company has been named in the Corporate Excellence Awards 2025. We heard more from Ralf Negele, CEO of Negal Engineering, below.
Operating for more than three decades, Negal Engineering is a Swiss-based company that specialises in advanced power electronics. Since its inception, this leading company has been on a mission to realise high-end circuit solutions for demanding applications – often those that had been deemed impossible by its peers. As a result, Negal Engineering enjoys a stellar reputation throughout the industry, renowned for its innovative flair and exceptional engineering capabilities.
Negal Engineering develops complex power electronic systems using state-of-the-art semiconductor technologies and custom circuit topologies. By using the latest silicon carbide, or SiC, and gallium nitride, or GaN, semiconductors in combination with intelligent digital control, circuit losses are dramatically reduced and efficiency substantially increased. With this, Negal Engineering’s strength lies in the development of customised solutions that meet specific requirements and form factors, and has spent numerous years developing specialisms, in which it has built a wealth of expertise.
Over the years, Negal Engineering has developed a number of groundbreaking solutions. The company, however, is best known for its core competencies and innovations, which have enabled the company to revolutionise the landscape of power electronics. Such competencies include active rectification systems for wide voltage ranges, marketed since 1995; ultra-fast power supplies that are capable of adapting to voltage changes of up to 4,000V within 200 microseconds; and shock wave generators used in medical applications, generating 4kA pulses at 25,000V for bone and wound healing support.
“Bridging the toughest energy challenges, Negal Engineering delivers solutions where others see impossibility. From pioneering renewable energy storage to revolutionising power electronics, our innovations drive efficiency, sustainability, and reliability – reshaping industries and empowering a cleaner, more resilient energy future.”
Negal Engineering places a great emphasis on quality assurance, allowing it to guide its processes to ensure client satisfaction. This pushes its team of expert engineers to not only design circuits but also accompany clients through the full development cycle – from concept and functional specification through to production readiness. This also includes the transfer of a finished development to series production. Negal Engineering remains invested in the quality of its products from its very inception right through to the end of its life cycle.
During the development phase, its engineers will provide both advice for optimisation and the EMC-specific circuit design, which will then be verified with the appropriate measurements. Electronic assemblies must meet ever-evolving requirements in terms of efficiency, costs, and emissions. In order for a product to be placed on the market on time and successfully, all normative guidelines must be met in addition to technical specifications.
As a result, the company understands the importance of appropriate documentation when ensuring consistent quality and strives to maintain the highest standards in compliance. Negal Engineering is certified to ISO9001:2015, a quality standard it allows to guide its daily operations. This not only enables Negal Engineering to maintain its exceptionally high standards but also paves the way for future innovation.
Alongside its inimitable innovation capabilities, Negal Engineering has become a key player in the market for its approach to client-centricity. In addition to receiving continuous communication and support from Negal Engineering, clients can feel reassured that the company will always use the latest technology to develop its solutions.
This is advantageous for the client, but poses a challenge for Negal Engineering, in which the company must learn the correct use of such new technologies. Obstacles are merely opportunities for growth for a company such as Negal Engineering, who remains committed to working tirelessly until it has achieved its client’s end goal. As Ralf proudly told us, “We simply don’t give up until everything works.”
“Sometimes we have to take a different path to what we had initially planned, but we have always achieved our end goal.”
Most recently, Ralf told us that Negal Engineering encountered a challenge within one of its projects. The company was tasked with developing a railway converter that was capable of handling a higher voltage while incorporating state-of-the-art technologies, specifically SiC. SiC, or Silicon Carbide, is a cutting-edge material often used in power electronics due to its efficiency, high thermal conductivity, and ability to operate at higher voltages and temperatures in comparison to traditional materials. While the integration of the SiC series circuit presented unique challenges, these were successfully overcome through extensive research and innovative engineering solutions.
This is just one example of Negal Engineering’s prowess; since 1995, the company has already implemented sophisticated control and power electronic solutions for more than 50 different companies, with its customers now successfully utilising these solutions worldwide. These solutions have enabled clients around the world to distinguish themselves from their competitors with the most demanding requirements, which would not be possible using the standard products available on the market.
In fact, a client of Negal Engineering said of its work: “Negal Engineering is a very competent company in the field of high-end power electronics, which successfully implements projects for customers all over the world – whether in the field of industry, mobility, or LED lighting, etc. Ultimately, Negal Engineering delivers classic Swiss engineering work that can compete on a global stage.”
Negal Engineering aims to persist in pushing the boundaries of power electronics whilst actively contributing towards environmental sustainability and grid efficiency. The company has already developed a number of sustainability and future-focused projects, including wind turbine inverters, scaled from home use to several 100kW; DC/DC converters for efficient DC bus networks, which are key to integrating PV, EV, and future salt-battery technologies into homes and industries; and the ongoing UK project of AI-controlled home energy systems, enabling energy storage and smart grid stabilisation.
Moving forward, the company will continue its work on solutions for domestic and industrial energy storage, as well as focusing on environmentally friendly solutions revolving around the use of salt-batteries. Such dedication to innovation and ongoing improvement has enabled Negal Engineering to shine in the industry as a key player, a company more than worthy of its title of Best Power Electronics Solutions Manufacturer 2025 – Switzerland.
