The Army is committed to hybrid electric combat vehicles for deployment in the next century. The key consideration for such systems is to minimize system volume, since interior vehicle volume, particularly under armor, is at a premium. A variety of power converters are required. It is therefore beneficial to reduce converter volume as much as possible, yet maximize efficiency, versatility and maintain high power quality. In a prior study[
The ARL effort is examining the effect of various types of solid state switches, including MOS Controlled Thyristors (MCTs), MOS Turnoff Thyristors (MTOs) and the advanced switches being developed under the Power Electronic Building Block (PEBB) program. The operational characteristics of each type of switch, such as commutation and conduction losses, and their effect on thermal management and the implications on vehicle mounted cooling system requirements are also addressed. Power quality issues are also examined in detail.
