    This paper presents design and control a suitable power electronics transformer (Solid State Transformer, SST) that is suitable for applying to be application in solar farm in Thailand by using Power Simulation Version 9.1 (PSIM 9.1). SmartCtrl is a toolbox of the PSIM 9.1 program that is used to design PI controllers and find the optimal gain automatically. The advantages of designing a controller with SmartCtrl are used to interface or work with other applications, simplified to use and not complicated, simulation results are easy to understand and analyze, and the controller from the design is stable. The PI controller from the design from the SmartCtrl to for using with Solid State Transformer in solar farm applications work satisfied and very well as confirmed by the simulation results.

    This paper presents a suitable power transformer for solar farm applications. Losses and economic value of the proposed transformer are compared to those of the standard transformer, for the application to a 1 MW solar farm, to help the solar farm owners select the best solution for their business. In this paper, a power electronics transformer called a Solid State Transformer (SST) is also proposed for the application to the solar farm because of its light weight, small size and varieties of functions. There are no core losses during no operation period which is about 15-16 hours a day.
