|Development of an Integrated Power Controller Based on HT SOI and SiC|
|Keywords: SOI, SiC, Power Controller|
|This paper covers the need for and feasibility of an integrated high-temperature Silicon-On-Insulator (HT SOI) power controller for an efficient Silicon Carbide (SiC) based power system. Such integration takes advantage of the best of HT SOI design coupled with the greatly enhanced power handling capabilities of silicon carbide. The end results will reduce the size of future power controllers while increasing reliability and efficiency. An integrated module will quicken the commercial adaptation of energy saving SiC technology. The need for High Temperature (HT) electronics is growing, and as such many more companies are developing HT components and sensors. With the products available today from companies such as Honeywell, Cissoid, SemiSouth, CREE, Quartzdyne, Kulite, TRS, Kemet, Novacap, a wide variety of HT qualified high power control systems can be developed. Examples include: Flexible AC transmission Systems (FACTS) controllers, Solid State Circuit Breakers, Fault Current Limiters, power supplies, Uninterruptible Power Supplies (UPS), hybrid electric vehicles, Distributed Energy Resources such as geothermal, solar and wind, and industry motor controllers. A prototype high temperature power controller has been designed and demonstrated to operate successfully up to an ambient temperature of 240C. It can be used as the basic building block for power converters, motor controllers, and a host of industrial control applications. The HT controller has the capability of monitoring the temperature at several key areas throughout the system (for diagnostic purposes) and demonstrates two basic functions: 1) inverter that provides the ability of interfacing with an inductive load, and 2) software controlled fault limit. These functions demonstrate two key attributes needed in a controller (managing an inductive load and demonstrating the capability of an “active” circuit breaker).|
