7. Engineering Excellence through Inimitable Innovation 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 highend 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.
