A NOVEL DC - DC CONVERTER APPLIED IN SOLAR ENERGY SYSTEMS FOR LOW & HIGH VOLTAGE DC APPLICATIONS

presently now a-days because of the deficiency of electrical power, increasing expense of non-sustainable power source assets producing electric power from the sustainable power source assets, for example, PV modules are expanding every day. This venture presents PV based framework which comprises of front end converter and a hack end converter used to holster high voltage and low voltage loads. The front end converter is a non-separated, high stride active DC- DC converter using half and half transformer with for low voltage sustainable power source assets solicitations. The suggested converter uses half breed transformer to exchange the both inductive - capacitive vitality at the same time, accomplishing high stride up voltage with littler measured attractive segment, the kill impairment of difference is limited, growing the adequacy of the converter underneath all heap situations. By swapping the info voltage the voltage weights on the dynamic switch and diodes remained kept up at stumpy level and are free accordingly of the resounding capacitor exchanging vitality to the yield of the converter. In view of extraordinary system capability in addition furthermore capability to work by an extensive variable input voltage, the suggested DC-DC converter stands an alluring arrangement in place of substitute low DC voltage imperativeness sources, for instance, sun situated PV modules and power gadgets. Though back end converter is a solitary switch buck converter which used to venture down the vitality from that point it provided to low voltage loads upto 30V DC. A pi based criticism control framework is connected to back end converter to accomplish fancied load needs. Numerical demonstrating of PV board, the most extreme power point following is utilized create the greatest power by incorporating a gating PWM to front end converter. All framework is displayed in Matlab/Simulink and results are checked.
