近年来，SiC和GaN，即所谓的宽带隙（WBG）功率器件，已开始进入市场。因此，需要更复杂的封装技术来最大限度地提高WBG器件的性能。Power-Overlay-kilo-Watt（POL-kW）是一种适用于高功率应用的先进封装。采用POL-kW和现有封装的功率模块的物理模型比例比较证明了POL-kW的电气和热优势。与半桥功率模块（POL-kW）和现有封装相比，POL-kW模块体积减小了50%，导热系数提高了20%，并且实现了较低的关断浪涌电压。
In recent years, SiC & GaN, so-called a wide bandgap (WBG) power devices, have begun to be introduced into the market. More sophisticated packaging technology to maximize the performance of WBG devices are required accordingly. Power-Overlay-kilo-Watt (POL-kW) is an advanced package for high power applications. Physical model scale comparison of power modules between employing the POL-kW and the existing package demonstrated the electrical and thermal advantage of POL-kW. Compared to Half-bridge power module with POL-kW and existing package, the module with POL-kW offered 50% volume reduction, 20% thermal conductivity improvement, and lower turn off surge voltage were realized.
