Abstract:In this paper step up DC-DC converter with different output voltage level for DC micro-grid application is proposed. The wide utilization of renewable sources, have significantly improved the diffusion of distributed generation unit changing the operations of distributed grids from passive networks to micro-grids. This paper analyses step up dc-dc converter with input from the DC source/ photovoltaic array and two DC output at different voltage level. The paper includes operation of proposed converter with different operating modes, the mathematical expression and the simulation results.
Abstract:In this paper, the design of Single Ended Primary Inductance Converter has been discussed for photovoltaic applications. This paper contains the modelling and simulation of solar cell using MATLAB/SIMULINK software. Maximum power point tracking has been discussed based on perturb and observe algorithm technique.
Abstract:The proposed model of dual output converter is presented based on CUK and SEPIC converters. The dual output of a single input voltage source is useful in various applications, like DC micro grids, Electrical machines, Solar Energy systems. The proposed converter requires less number of inductor and capacitor as it is compared with the separate converter. The proposed converter is useful regarding the different output polarities. In addition, this converter can be used as multiple voltages power supply. The converters analysis is carried out in continuous current mode. The proposed converter is simulated both in open loop and closed loop using MATLAB/SIMULINK model.
