In search of optimizing its railway maintenance operations, our client was facing a technical challenge. In this article, we delve into this project designing a DC/AC Inverter to provide a solution to work with different power supply frequencies. Read more
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 most common challenges at Premium PSU we face.
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 equipment in trams and trains, we will be focusing on the EN50155.
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 to start the diesel engine in diesel-electric hybrid trains.

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 power and 400 Watts peak power. Read more
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.

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.
