This proposed paper presents the study of power electronic transformers and their application for solar farms. The structure of the power electronic transformer consists of both primary and secondary converters and the high frequency transformer. The ferromagnetic core is chosen for the design, whether in terms of performance, size and cost. The application of the power electronic transformer replacing the low frequency transformer with the converters is applied in the solar farm. It also discusses the transformers that are suitable for using in solar farms, including a comparison of advantages-disadvantages and analyzing the economic value of the power electronic transformer with the conventional system consisting of an inverter with a low frequency transformer. It is found that if the return value was not lost due to the core loss of the transformer, it is deducted from the investment value. The power electronic transformers are going to be worth a higher investment than the original system consisting of inverters with low frequency transformers. But to get a new operating system that has more functionality and more intelligent systems that will be in the future as well.
