4 Xantrex RE/Backup Power Product Portfolio Single Phase Grid TieGT2.8GT3.3GT4.0GT5.0Battery Based ProductsThree Phase Grid TieTrace SeriesC-SeriesXantrex covers all Distributed Power application segments with a wide portfolio to service both residential, commercial and utility customers. For utility Backup Power applications, Xantrex offers a complete product range. From 500 watts for single critical load backup, to mid-range 2500 or 5000 watt units for multiple critical loads, to complete “whole house” solutions with automatic operation to keep all critical loads running smoothly in the event of a power outage, Xantrex has a product to fit almost any Backup power need.Wind and solar photovoltaic energies have emerged as commercially viable sources of distributed power in industrial and utility environments. Xantrex is a premier designer and manufacturer of 3-phase power conversion systems for wind turbine OEMs and solar photovoltaic systems integrators that range from 10kW to 1.5MW.The following Xantrex products are available:Solar Photovoltaics: Inverters for commercial and industrial scale grid-connected Photovoltaics from 10kW up to 500kW. Also Xantrex offers turn key solutions for solar applications up to 1000kW. For larger PV systems, any number of PV inverters can be paralleled at the point of utility connection.Wind power conversion systems for utility-scale: Xantrex offers custom OEM power system components to wind turbine designers and manufacturers for the development of reliable, cost-effective power conversion and control solutions. With experience in the control of singly-fed asynchronous, doubly-fed asynchronous and synchronous generators from a 10 kW to 1.5 MW ratingDetailed background on Industrial & Utility Solar Photovoltaic:Product offering based on PV Series and GT Series are utility-interactive, three phase inverters from 10 kW to 500 kW.PV Series inverters transfer power between the DC output of a PV array to the AC utility. Xantrex established a North American standard as the first company to provide a standardized UL1741 listed three-phase PV inverter for use in light industrial/commercial applications. PV Series inverters are extremely efficient, operating at 96% efficiency at full rated power. They are equipped with automatic array optimization, peak power tracker, LCD display, and utility protection functions. UL listed models with 10, 15, 20, 30, 45, 100, 225 kW power ratings are currently available. For utility "behind the fence" applications, Xantrex offers non-listed models with 150, 225 and 300 kW ratings.With focus on the international markets, Xantrex introduced during 2004 the new GT Series platform for Europe – the GT100E and the GT500E, 100kW and 500kW respectively.Detailed background on Industrial & Utility Wind Business:Production cost of wind-generated electrical energy has fallen dramatically in recent years. In many cases, rates are below conventional thermal power plants. As a result, demand for utility scale wind plants has increased. Worldwide wind power capacity exceeds 17,000 MW. More than half of this capacity was installed within the past three years.Xantrex power conversion technology takes part in providing more than 2,000 MW of energy created by variable speed wind turbines. Variable speed wind systems allow the speed of the wind turbine rotor to vary. They provide increased aerodynamic efficiency, greater energy capture, reduced mechanical and structural loading, power factor control, and other benefits that traditional constant and dual speed turbines cannot deliver. The most advanced wind machines are based on variable speed technologyXW SeriesGT100GT2504

35 Designed for Reliability Using Insulated Metal Substrate in Power Bridge AssemblyIMS is proven technology commonly found in motor drivesCapacitors are widely distributed and load share to minimize stressReliability BenefitsSuperior heat dissipationLow electrical impedanceEfficient mechanical designCapacitors are distributed on DC Link Filter Board to keep traces b/w FETs and Caps as short as possible to minimize the parasitic inductance and associated switching losses. Lots of caps are used in order lower the thermal stress on each cap. If one cap fails, the unit will still remain operational. Expected failure mode is due to aging.
