Much like the Internet, the Smart Grid will consist of controls, computers, automation, and new technologies and equipment working together with the electrical grid to respond digitally to quickly changing electric demand. From smart meters to energy gateways, power electronics is an extremely important element in modern smart grid systems. In the modern electric power grid, power electronics is indispensable in high-voltage dc (HVDC) system, static VAR compensators (SVCs), flexible ac transmission system (FACTS)-based active and reactive power flow control, uninterruptible power system (UPS), fuel-cell-based energy system, etc.
Semiconductor-based power electronics are playing a major role in smart grid devices by reducing power consumption and ensuring proper signal propagation. Power electronic solutions from Rogers offer robust reliability and efficiency for these devices and Smart Grid Technology.
For Smart Grid semiconductor applications, inside the IGBT and MOSFET power modules, power substrates from Rogers enable interconnections and provide cooling. Our curamik® ceramic substrates are designed to carry higher currents, offer higher voltage isolation, and can operate effectively over a wide temperature range. High heat capacity, conductivity and thermal spreading of the thick copper cladding make curamik substrates ideal for power electronics where reliability is critical. The silicon chips mounted directly on the substrate (Chip on Board) yield low mechanical stress. This is because the coefficient of thermal expansion (CTE) of the ceramic substrate can be matched to the CTE of silicon.
ROLINX® busbars enable high reliability power distribution for components within smart grid applications. Between the power source and capacitors, integrated gate bipolar transistors (IGBTs), or complete modules, these laminated busbars deliver a customized liaison. Our laminated multilayer busbars are flat and compact, while offering low inductance, controlled partial discharge and high current capabilities.
