TI公司的TIDA-010210 6.6kW三相三级ANPC逆变器/PFC上向功率级参考设计,提供实现三级三相碳化硅/氮化镓(SiC/GaN)基于ANPC逆变器功率的设计模板.采用超快功率器件使得开关频率高于100kHz成为可能,从而降低滤波器所用磁性元件尺寸和增加功率级功率密度.多级拓扑允许在高达1000V的更高DC总线电压上使用600V额定的功率器件.较低开关电压应力降低了开关损耗,导致峰值效率高达98.5%.设计是模块化的,使得用同样的滤波器级可配置和SiC或GaN功率器件一起工作.主要用在太阳能串型逆变器,太阳能集中式逆变器和能量存储电源转换器(PCS).本文介绍了参考设计TIDA-010210主要特性和指标,框图,以及ANPC三相逆变器架构图,电路图和材料清单.

 

This reference design provides a design templatefor implementing a three-level, three-phase, siliconcarbide/gallium nitride (SiC/GaN) based ANPCinverter power stage. The use of fast switching powerdevices makes it possible to switch at a higherfrequency of 100 kHz, reducing the size of magneticsfor the filter and increasing the power density ofthe power stage. The multilevel topology allows theuse of 600-V rated power devices at higher DCbus voltages of up to 1000 V. The lower switchingvoltage stress reduces switching losses, resulting ina peak efficiency of 98.5%. This design is modular in

construction, making it configurable to work with SiCor GaN power devices with the same filter stage.

This reference design is built in a modular construction to allow easy replacement of power switching devices toallow..
