N2 - The operation and control for a three-phase to three phase grid-connected solid state soft switching transformer based on Lyapunov energy function has been presented in this paper. Soft switching solid state transformer has been reported in various literature for dc-ac, dc-dc and also ac-ac applications. The overall structure of the converter is based on current source inverter type of topology with an intermediate high frequency transformer, thereby making it immensely difficult to control and operate optimally. In this paper, possibility of controlling such a converter based on Lyapunov energy function has been explored for power transfer between two points in an ac power system without intermediate dc link. Lyapunov energy function based control architecture provides global stability and better tracking performance over traditional control architectures. The proposed control architecture is verified via computer simulations based on MATLAB/Simulink and PLECS domain and various case study results are obtained to verify its efficacy.
