A dual mode time-sharing inverter has higher efficiency than other type grid-connected inverter due to only one power stage of it working in high frequency state at any time. In this paper, small signal modeling of this inverter is carried out, which reveals that the control-to-grid current transfer function of this inverter has a right half plane zero at low frequency during the “Boost” operating stage which results in the difficulty in controlling the system. An indirect current control… CONTINUE READING
