The concept of redundancy is simple: having a repeated system so, in case of a single failure, there is always an alternative. AC redundancy usually refers to all extra-high voltage lines available that can operate in case of mainline failures. However, we mean redundancy when we have more devices than the minimum required.

Medium voltage installations are a critical part of the electrical distribution system and having reliable protection is vital, as is communications. At Premium PSU we have faced the challenge of providing a safe DC line to the protections and communications of medium voltage substations.
Railway transportation is one of the fastest and less polluting forms of transport in the world. Within the EU, it is responsible for less than 0.5% of transport-related greenhouse gas emissions. In this process, power electronic companies have the mission to design technologically advanced solutions to create increasingly lighter, more efficient, safer and more reliable trains.
In aeronautics, it is essential to provide energy solutions that combine power and lightness in order to ensure the correct and constant power supply to all the electronic components of the system. Read more
At Premium PSU, we have recently helped to promote an innovative micro-mobility project to charge electric bicycles. Do you want to know how? Promoting sustainable mobility is a priority and a challenge for the smart cities of tomorrow. Read more
Making devices more autonomous is becoming a key factor in making technology smarter, and this is what Les Companions do with their autonomous robot, an innovative assistant for painters that not only paints but also sands and assists professionals in their daily tasks.
Due to its many advantages, among which zero emissions stand out, the fuel cell is beginning to position itself as an alternative for the generation of sustainable energy. In this process, power conversion systems are essential to shape new applications using clean energy sources based on hydrogen. Read more
Power supply for rolling stock can be critical, especially in emergency-related applications such as HVAC systems, where a ventilation circuit is needed for safety and passenger comfort reasons when a train loses its main power source (catenary or diesel motor) in the middle of the route.
