exPeRIeNCeDTRIAL By FIRe FOR KAOHSIUNG MeTRO
Low weight was the key requirement for the aux-iliary power converters in Kaohsiung Metro’s vehicles. This criterion was set by vehicle manufac-turer Siemens in 2004 and the formative factor for the design of the first generation SMARTconverter. SMA Railway Technology GmbH realized the weight reduction through medium-frequency galvanic sepa-ration and delivered a total of 84 auxiliary power converters for the 42 three-car metro trains ordered by Kaohsiung Rapid Transit Corporation (KRTC).
Almost four years after receiving the order, the SMARTconverter successfully proved itself in passen-ger service in the tropical climate of the city of a mil-lion people. The underfloor devices are installed in the
28 kilometer long “Red Line” and in the 24 kilometer long “Orange Line” that opened in 2008. Both the red line, which provides north to south service, and the or-ange line, which travels east and west, have become the most popular means of transport in the island’s second largest city.
Kaohsiung’s cityscape is characterized by modern build-ings, glass and steel skyscrapers as well as pavilions, temples and shady places such as the terraces on the Longevity Mountain, the Shoushan, all of which invite both tourists and inhabitants alike to stay and enjoy.

When thinking about Spain, the first thing that may come to mind are the long white beaches of the Costa de la Luz in the south of the country. But while the rough northern Atlantic coast is quite different, it is equally as interesting. It can be discovered when traveling on a EuskoTren (Eusko Trenbideak Ferro-carriles Vascos S.A.) train, a commuter train oper-ating company. The journey, on electrified narrow-gauge tracks with a width of 1,000 mm, starts in the French provincial town of Hendaye and continues via San Sebastián to Bilbao.
Hendaye (Basque: Hendaia) is the most south-westerly town of France. Thanks to its location by the sea and
its fine sandy beach, it is very popular among water sports enthusiasts and sun worshippers. San Sebastián or “Donostia”, as it’s called in Basque, is only 20 kilometers from the French border. The town captivates its visitors with its shell-shaped beach, La Concha, and its elegant seaside promenade. Beautiful mansions are reminiscent of the magnificent seaside resorts of the last centuries.
When walking through the old town, people are amazed by the distinctive architecture of the town. The Plaza de la Constitución is considered to be one of the most beautiful city squares of Spain. When leaving the city by train towards Bilbao, you travel through beautiful landscapes of lush green, grazing cows and secluded

sandy beaches. The picture changes as soon as travelers approach Bilbao.
With a metropolitan area of nearly one million inhabi-tants, Bilbao is not only the largest city of Basque Coun-try, but also the most important industry and port city in the Gulf of Biscaya. Travelers arriving by train can get off at one of the stations located directly in the city center.
SMA Railway Technology GmbH manufactured 30 of its proven auxiliary power converters for the Spanish com-muter trains. The technology of these second generation SMARTconverters remained unchanged, but with opti-mized flexibility thus resulting in improved maintainabil-
ity. This was one of the reasons the vehicle manufacturer CAF decided to order this extremely flexible and compact SMARTconverter version for euskoTren.

HIGH FReqUeNCyFROM INNOVATION TO STATe-OF-THe-ART TeCHNOLOGy
Even 20 years ago, developments in auxiliary power converters focused on the demand for low dimensions and weight, higher efficiency and simpli-fied maintenance. With the increasing availability of IGBTs as semiconductor switches, new auxiliary power converter switching concepts were devel-oped that better allowed these requirements to be met. Thanks to the relatively low control effort, as compared to thyristors, as well as higher switch-ing frequencies, new switching topologies could be developed. It soon became clear that the operating frequency increase of the transformers necessary for galvanic separation played a key role in the auxiliary power converters design.
All auxiliary power converters with medium-frequency galvanic separation are based on replacing the separating transformer used in conventional devices that is operated with the respective AC network frequency with a trans-former with an operating frequency in the kilohertz range. As this can significantly reduce the transformer’s weight, it therefore also has a direct impact on the auxiliary power converter’s total weight.
At the same time, the technical progress has made the need to adjust the switching topology more manageable. Consequently, auxiliary power converters with medium-frequency galvanic separation have become state-of-the-art technology.
For SMA, the age of medium-frequency galvanic separa-tion started as early as 1993 with the development of battery chargers for the Deutsche Bahn’s Interregio trains. In 1999, SMA introduced the Mee-NT platform as the basis for complete auxiliary power converters with medium- frequency galvanic separation. At first, multi-voltage auxiliary power converters from the SMARTconverter product family were used in refurbished passenger cars in service throughout europe. Since 2001, the concept has also been applied to single-voltage SMARTconverters. The lot sizes have continuously increased. By 2010, a total of
700 SMARTconverters with medium-frequency galvanic separation has been delivered.
Throughout the years, thanks to medium-frequency galva-nic separation, the auxiliary power converter’s functional-ity could be enhanced. For example, the frequency of the supplied AC network is now almost arbitrary. The output voltage is available over a significantly broader input volt-age range and active filters for the auxiliary power con-verter’s input voltage can be generated. At the same time, the demand for systems allowing for improved maintain-ability and easier integration has consistently increased.
At the InnoTrans 2010, SMA presented the second gen-eration SMARTconverter for the first time. It represented a complete overhaul of the device platform with regard to flexibility, diagnostics, maintenance and repair. The mod-ules, cabling and container were completely redesigned. In only two years, approximately 700 devices of this type were delivered to customers worldwide. Whereas in the past, a large part of the deliveries was for refurbishment projects, the share of new-build projects has grown rapidly over the last few years.
In the meantime, auxiliary power converters with medium-frequency galvanic separation have become state-of-the-art. With the SMARTconverter product family, SMA offers single- and multi-voltage auxiliary power converters for various input voltages and power ratings. The portfolio is completed with battery chargers from the SMARTcharger product family and SMARTcooler air conditioning systems which are equally based on the Mee-NT platform.

Fast-growing panama is boosting its infrastructure. Apart from expansion of the airport and the Cinta Costera project, which includes extension of the panama Canal and coastal strip, a new metro sys-tem is being built in panama City. The gross domes-tic product of this transit country has been continu-ously growing since the middle of 2002. In 2011, it increased by 10.5 percent and the forecast is 8 percent for 2012.
The excavation under way in Panama City started in the beginning of 2012. Huge machines are digging tunnels for the new subway system leaving massive amounts of soil needing to be excavated, transported and disposed of and building materials to be procured. The metro line will run 14 km though the traffic-congested capital.
Line 1 will have 16 stations, 11 of which will be under-ground to help alleviate stress on Panama’s infrastructure.
STRONG GROWTHPANAMA IS exPANDING ITS INFRASTRUCTURe
The six-car metro vehicles of the fleet for the $1.5 billion metro project are being built by the system manufacturer Alstom.
The nearly 100 meter long trains will start service in 2014 and will travel from Los Andes in the northern part of the city to the Albrook bus terminal. Second generation SMARTconverters will transform the input voltages of the vehicles from 1,500 V DC into the required output volt-ages of 3 x 220 V AC, 60 Hz, 127 kVA and 72 V DC, 18 kW. Up to 30,000 passengers can use the metro at peak times and the ride from the first to the last station will take 23 minutes.

SeTTING STANDARDS INNOVATION-DRIVeN
Auxiliary power converters with medium-frequency galvanic separation provide many technical ad-vantages. Thanks to their lower weight, reduced dimensions and increased efficiency, they bolster significant energy savings throughout the lifetime of the vehicles.
Today, as a result of many years of successful application in daily passenger service and continuous development, auxiliary power converters with medium-frequency galvanic separation are as reliable as conventional systems. Further-more, modern redundancy concepts have contributed to the steady increases in the availability of onboard supply systems’ rolling stock.
The procurement costs of auxiliary power converters with medium-frequency galvanic separation have equally been reduced. As a direct result of the small amount of material used, particularly aluminum and copper, the prices have be-come significantly less dependent on increasing raw material prices than in comparison to conventional devices.
Further savings potential can be attributed to electronics in-novations, especially those made in power electronics in the last years. Thus, at present, it can already be said that at least in europe, auxiliary power converters with medium-frequency galvanic separation no longer represent a cost disadvan-tage. There is no doubt that these systems will also establish themselves in markets for localized devices such as in China

or India. Against this background, SMA has once again opti-mized the SMARTconverter. The now even lighter and smaller auxiliary power converters are still based on the Mee-NT platform, but they include redesigned switching concepts.
Because of the high demand for SMA auxiliary power con-verters, offering standardized products manufactured with-out much effort in large numbers for the international market becomes increasingly important. The universally applicable auxiliary power converter will meet all legal and normative requirements of major markets.
Apart from providing standardized systems, this includes providing customer-specific service based on a worldwide
network of service partners and subsidiaries to meet the de-mand for local added value.
SMA subsidiaries in Brazil and China as well as the manu-facturing partners in India, Turkey, South Africa and the U.S. ensure immediate and direct customer service and reduced delivery times. Would you like to know more about the new SMARTconverter? Please feel free to contact us.
