分布式寄生电容对高频高密度三相Buck整流器影响的分析与改进

For high-density three-phase buck rectifier (3ph-BR), such as a standard full-brick size 3ph-BR, there exist obvious parasitic capacitances distributed between its dc-link output and the system ground, which lead to low-frequency distortion of input currents, and thus, serious deterioration of the input current total harmonics distortion (THD). The effect of the distributed parasitic capacitances ...
