电力电子牵引变压器中双有源桥DC-DC变换器的多速率数字信号处理与噪声抑制

Power electronic traction transformer (PETT) is a single-phase ac–dc conversional system, which is made up of a cascaded H-bridge converter and output-parallel dc–dc converters, such as dual active bridge dc–dc (DAB) converters. As the voltage fluctuation of the dc output voltage of DAB converters is very small and the gain cross-over frequency of the open-loop transfer function of DAB converters ...
