基于SiC功率器件的低电压应力与快速响应高精度软开关变换器

Due to the characteristic of no blanking time, dual buck topology is attractive in high-precision applications and the bias current is injected to eliminate zero crossing distortion. However, with the extension of bus voltage, it is difficult to ensure the current response speed and accuracy due to the limitation of bias current operation and the impact of parasitic parameters of switching devices...
