The rail industry is now more than ever the perfect opportunity for power electronics
Power Electronics for Rail Applications, the new report from Yole Développement.
Yole Développement announces its Power Electronics for Rail Applications report. Yole Développement’s report focuses on the rail industry. Yole Développement Power Electronics team analyzes how this industry is structured, its market and players and technological developments that will impact the power electronics market.
A power electronics market that will be multiplied by 1.7, reaching $4.5 billion by 2020
Moreover, emerging regions such as South America, Africa/Middle East and Southeast Asia are demanding more and more in terms of public transportation.
The related inverters market for public transportation is today estimated at $3 billion, and is expected to reach $4.5 billion by 2020. In this new report Yole Développement shows how and why rail is dynamic, with the main reasons being commuter trains and related EMU architecture As a consequence, the power electronics market represents an excellent opportunity for revenue generation in high-end systems, both in terms of semiconductor-based components and passive ones.
The rail industry’s expected technological developments occur at every level
Therefore, the rail industry both suggests and benefits from major developments, especially in power electronics.
We see evolution from a systems point-of-view:
The key parameters for SiC adoption are high-voltage device availability (up to 10kV), cost reduction, guaranteed reliability and the fact that huge improvements can be made in the rail industry with SiC. Currently, switching devices and diodes are Silicon-based (IGB T almost exclusively for transistors). Only a few thyristors are used for basic and old locomotive designs.
The train industry supports local and global players
First, Yole Développement sees more and more joint ventures and worldwide partnerships driven by the “three big ones” (Alstom, Siemens and Bombardier). In fact, they require a presence in the dynamic regions of the globe, and at the same time they transfer some of their tech knowledge to local companies. The recent example of Alstom and Transmashholding in Russia is an accurate depiction of how important it is to be global.
The case of Chinese companies like CSR and CNR is also valid: over the last decade, they have created partnerships with the major European and American companies in order to access technological knowledge.
Furthermore, vertical integration is habitual. Like almost every power electronics application, it is synonymous with internal knowledge consolidation and cost reduction. Large players – when not contracting smaller players, i.e. CAF with Trainelec in Spain – have internal divisions representing motor and gear manufacturing, inverters, power electronics pantographs, etc.; all of this knowledge internal! The Russian leader Transmashholding and its 14 subsidiaries are a prime example of this “internal accumulation of knowledge”. Another example is the acquisition of Dynex by the Chinese giant CSR, which makes CSR the first Chinese company to master IGB T die manufacturing.
In a nutshell, as diverse and as inaccessible as it may look, the rail industry is now more than ever the perfect opportunity for power electronics: a clear, safe and innovative future is unfolding.
