Topology and Control of High Transformation Ratio and Large Capacity DC Transformer Based on Multi level Current Source

The replacement of traditional fossil fuels with new energy sources is a prevailing trend in global energy development. As the demand for electricity continues to rise worldwide, new energy generation is increasingly deployed in large-scale and clustered forms. Developing DC grid technologies—based on DC collection and DC transmission—is essential for supporting the large-scale delivery of renewable energy. As one of the core devices in DC grids, highvoltage and high-capacity DC transformers play a crucial role in DC voltage conversion and
