In the traditional AC transmission method, there will be a loss of reactive power in the cable. If we use the DC specification, this loss can be reduced to improve the efficiency. There is a need for voltage transformation between 40020k VDC. The disadvantages of traditional transformers are large size, heavy weightpollution of insulating oil. The demand for solid-state transformers came into being. Our solution utilizes ISOP＇s modular architecture to increase the frequency to 50 kHz to achieve the effect of reducing sizeimproving efficiencycan improve the shortcomings of traditional transformers.

The plan of ISOP＇s modular architecture, coupled with the application of solid-state transformers, the input of two sets of 10 k VDC are connected in series,the output is connected in parallel to achieve voltage conversion between the medium voltage side voltage of 20k VDCthe low voltage side voltage of 400VDC. This solution increases the frequency to 50kHz to achieve the effect of reducing the volumeimproving the efficiency,can improve the shortcomings of traditional transformers,is suitable for renewable energy of multiple specifications.
