Abstract

Control and operation of a three-phase solid state soft switching transformer based on Lyapunov energy function for three-phase standalone application has been presented in this paper. Soft switching solid state transformer is based on a current source inverter type of topology with a high frequency transformer, therefore, making the converter immensely challenging to control and operate optimally. Possibility of controlling a soft switching solid state transformer based on Lyapunov energy function under nonlinear loading condition has been presented in this paper. Various case study results along with the derivation of the Lyapunov energy function based controller has been elaborated in this paper. The proposed control architecture is verified via computer simulations based on MATLAB/Simulink and PLECS domain and various case study results are presented and discussed in this paper.
