Case studies by industry
At Premium PSU we have worked with projects from different types of sectors or industries. We highlight four main areas: Transport and Rail, High Tech, Energy and Extreme Environments.
Parallelizable DC/AC Inverter powering a crane motor
In today's dynamic industrial landscape, manufacturers constantly face unique challenges in meeting our customers' evolving needs. One such predicament arose when a prominent crane manufacturer was tasked with delivering a cutting-edge solution…
Railway AC/DC Battery Charger with IP65 for desert
Demanding climatic environments require much more rigorous custom solutions to offer the customer the same reliability as other stable contexts. A factor such as extreme temperature is a stress factor for all components and this is one of the…
Solutions at all levels in power conversion electrical energy – [Infographic]
Generation of energy The generation of electrical energy consists of transforming some kind of energy (nuclear, thermal, solar, among others) into electrical energy and is carried out in different stages. Power plants are the first actor in…
What is EN50155 for railway applications?
This article intends to resume the most important requirements that apply for power supply devices when considered as a component in railway applications. Although there are several standards to take into consideration when installing electronic…
Hybrid trains: A must-have converter to start up the diesel generator
In this new article, we want to introduce how our newest DC/DC converter CBS-10K works with a “Start-up diesel engine” application in the hybrid trains. The CBS-10K has been designed under rolling stock standards and is the perfect complement…
CVS-280: DC/DC low battery voltage starter
What are the key features and railway applications of the new CVS-280 DC/DC low battery voltage starter? This series is designed to operate directly from the 750V DC catenary line and can provide DC outputs from 24V to 110V at 280 Watts continuous…
ACB-3000: Providing AC Redundancy in DC/AC Inverters
What is redundancy in electrical systems? 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…
A safe line DC for medium-voltage substations
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…
Boosting Railway performance
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…
