Microgrids and their interconnection with main grid are gaining importance nowadays. Usually inverters acts as power interface between the renewable energy resources and main electrical network. This paper focuses on design and simulation of a simple and easy to implement controller for the operation of this inverter in MATLAB SIMULINK environment. This controller enables the microgrid to operate...
Digital feedback control of a full-bridge DC-DC converter, using a gain scheduled PI controller, is presented in this paper. Input voltage to the converter varies over a large range, as a result, controller gain designed for one particular input voltage may not give the optimum performance. Consequently, gain of the digital PI controller is made a function of the varying input voltage, and such a...
As far as the complexity of the current mode control is concerned, illogical choosing of the phase cross over frequency for a converter doesn't bring any significant advantages over the voltage mode control. So, one has to select the bandwidth carefully so that benefits of the current mode control will trade off with the complexity of implementing the scheme. The reported work emphasizes on the importance...
