Abstract

This paper proposes a new method using port controlled hamiltonian (PCH) model and energy shaping control method to study control issues of PV grid-connected improved Y-source inverter. State averaging method is adopted to transform the nonlinear system of the improved Y-source grid-connected inverter into a hamiltonian model. According to the control objectives of the system, equilibrium points of the system are determined, then the system controller is designed using interconnection and damping assignment method. Finally, a 200W laboratory prototype is built based on a TMS320F2812 digital signal processor to verify the performance of the control method.
