在过去的30年里，功率转换器的输出功率密度(OPD)一直以两位数的速度线性增长。商用功率转换器的OPD目前约为5W/cm3。20W/cm3至30W/cm3的高OPD功率转换器将于2015年左右问世。在设计高OPD功率转换器时，需要一种准确的电路损耗设计方法，该方法考虑了功率器件参数和电路杂散参数的影响。提出了一种用于高输出功率设计的精确的MOSFET开关损耗分析和计算方法
The output power density (OPD) of power converters has been lineally increasing by a factor of 2 figures in the last 30 years. The OPD of commercially available power converters is now at a level of about 5 W/cm3. The high OPD power converter of more than 20 W/cm3 to 30 W/cm3 will apear around 2015. For designing the high OPD power converter, an exact circuit power loss design method, which inclueds the influences of power device parameters and the circuit stray parameters, is required. A novel exact MOSFET switching loss analysis and formulation methods have been proposed for designing high output power
