| Abstract: | A novel single phase UPQC based on the structure of DC unit isolation is proposed. The DCI-UPQC is isolated from the power grid by parallel connection of several capacitors in DC-link unit instead of transformer isolation in series or parallel unit. The relations between indices of the device and parameters of the DC unit are analyzed. The control method of a DCI-UPQC is also proposed. In the end, the simulation and experiment results are given to validate the practicability of the topology and the effectiveness of the control method. |
