摘要
新型30 k W 电流模式 P W M 控制的功率变换器采用 N P T- I G B T 器件,无需串联隔直防偏磁电容,使用有源斜坡补偿技术,效率达到90% ,具有极好的动态响应、过流保护及模块均流并联性能,是一种具有极大功率扩容(可达到100 k W )潜力并易于工程化实现的 I G B T功率变换器。
Presented in the paper is a novel 30 kW current mode PWM controlled power converter.The converter,of which the efficiency reaches 90%,applies NPT-IGBT device and an active slope compensation technology with no need to series connect a DC blocking and bias proof capacitor.It features excellent dynamic response,over current protection,parallel module current equalization,very high power expansion potential(as high as 100 kW)as well as easy engineering realization.
