SiC material been long thought to be the ideal power semiconductor substrate materiall for the future of many power system applications but no one as been able to break the high cost barrier for a power switching device. SemiSouth, with its in-house SiC epi process technology and vertical trench JFET design has enabled a dramatically smaller chip size thus increasing the number of chips per wafer and bringing the cost down to levels that makes it viable against encumbant 1200V Silicon IGBTs.

SemiSouth is the only company in the world to offer a this normally-off JFET and it is currently being designed into next generation Solar Inverter platforms and many of the Top Solar Inverter companies in the world. This device is now “on the roadmap” of every major Solar inverter company in the world.
How do customers benefit ? Higher PWM frequencies in Solar Inverters at high efficiency (98-99%) thus enabling a substantial reduction in the cost and size of the output chokes, magnetics, heat sinks which will result in an overall lower cost for the Solar Inverter and reduces its size by over 50%.
The total weight (foundation, steel beam system and solar modules) amounts of approximately 120 tons. The SunDriver is fixed by 12 lift-locks, so it can withstand even extreme wind conditions. The design of the SunDriver system is based on high-quality components, which were developed and tailored to complement each other in an optimal way. This harmonization of all elements of the system produces higher synergies allowing superior energy yields.
The SunDriver system meets the highest industry standards on an international scale regarding the foundation, the lightning protection, the mechanics, the electrical components and processes and the communication engineering.

SunDriver™ S-600 the world’s largest tracking system
SunDriver Systems AG has developed the world’s largest solar power tracking system. A single system, called ‘SunDriver’ has a production capacity of up to 100 kWp of electrical energy with a solar module surface area of 650 m2
.
The SunDriver system, based on a 40 ton steel frame, upon which the solar modules are mounted, tracks the sun’s position utilising its rail system. The foundation, covering a diameter of 16 m, represents the base for a long-term structural integrity with its weight of approximately 70 tons.
The AMETEK Programmable Power TerraSAS System (TSAS)
The AMETEK Programmable Power TerraSAS System (TSAS) provides a programmable means of simulating the response of a PV array. The system provides a turn-key approach to testing the maximum peak power tracking (MPPT) characteristics for grid-tied inverters and DC charge controllers.
The ability to simulate virtually any fill factor or solar cell material allows the system to characterize the MPPT algorithm with a power source that duplicates the characteristic IV array slope for a wide array of fill factors. The simulated PV arrays are provided in terms of array fill factor, Maximum Power Point Voltage and Maximum Power Point Power. The curves generated are based on the Sandia Labs simplified PV Array model defining the relationship between these values and other parameters.

eIQ Energy vBoost Parallel Solar
eIQ Energy’s vBoost Parallel Solar architecture uses advanced DC power conversion and management technology to allow easy connection of solar panels in parallel rather than in series. The vBoost DC-to-DC converter attaches directly to solar modules and creates a parallel connection to a central inverter,
