TI公司的TIDA－010039是三级三相SiCAC／DC转换器参考设计,提供了如何实现具有双向功能的三级三相基于SiC的AC／DC转换器.其高开关频率50kHz降低滤波器设计中的磁性元件尺寸,从而获得更高的功率密度.SiCMOSFET具有低开关损耗,使得更高的DC总线电压高达800V,较低开关损耗具有峰值效率大于97%.参考设计的输入为380–400VAC峰值,DC输出为800V,在400-VAC50或60-Hz电网连接时,最大输出功率为10-kW,10-kVA,隔离驱动器ISO5852S具有增强的绝缘性能,用来驱动高压SiCMOSFET,而UCC5320S则用来驱动中等SiIGBT.采用AMC1301来监测负载电流,而TMS320F28379D控制卡用来数字控制.主要用在DC充电桩,电动汽车充电站功率模块,能量存储转换系统(PCS)和三相UPS.本文介绍了三相SiCAC／DC转换器参考设计TIDA-010039主要特性,框图和主要系统指标,以及电路图.

This reference design provides an overview on how to implement a three-level,three-phase,SiC-based AC／DC converter with bidirectional functionality. A high switching frequency of 50kHz reduces the size of magnetics for the filter design and as a result a higher powerdensity.SiC MOSFETs with low switching loss enable higher DC bus voltages of up to 800V and lower switching losses with a peak efficiency of>97%.

This design is configurable to work as a two-levelorthree-level rectifier.For design informationon the DC／AC implementation,see TIDA-01606.
