Demand Response Inverter (DRI)
Inverters incorporating advanced communications and integrated with energy storage are required in order to facilitate higher penetration of distributed generation on the grid. PPS is working with leading systems integrators, utilities, and technology providers to develop this next generation of grid-tied inverters, funded in part by the US Department of Energy and Sandia National Labs under the SEGIS program (Solar Energy Grid Integration Systems). Prototypes are in development today, and will begin commercial testing the first half of 2010 |

Silicon Carbide Semiconductor Devices
Silicon Carbide (SiC) has long been used as a cutting material, but is notoriously difficult to fabricate and process as a semiconductor material. PPS is working with global SiC experts to develop devices and packages for power converter applications, achieving spectacular gains in power density, efficiency, high-temperature and high-voltage capability. Combined with PPS’ advanced power conversion technologies, the SiC-based converters will far surpass anything available on the market | | |
